The goal of the forthcoming patches is to integrate AT_CONFIG into
Autoconf. But I need some code used in config.status, so let's first
cleanup general again (in which there are way too many things), i.e.,
split it, introduce that macro (_AC_SRCPATHS), and then create
autoconf/autotest.m4.
I also realize I made a serious mistake when I accepted this patch:
2001-06-23 Paolo Bonzini <address@hidden>
* acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): Defer parsing of
config.status targets to after the evaluation of the INIT-CMDS.
Double quote config.status targets (used to be single quoted).
because it result in having all the INIT-COMMANDS share the space
variable space name :( If two init-cmd say `my_var=something' and
`my_var=something-else', then it's doomed to failure.
If someone has an idea on how to solve this...

-## ----------------------- ##
-## Creating output files. ##
-## ----------------------- ##
-
-
-# This section handles about all the preparation aspects for
-# `config.status': registering the configuration files, the headers,
-# the links, and the commands `config.status' will run. There is a
-# little mixture though of things actually handled by `configure',
-# such as running the `configure' in the sub directories. Minor
-# detail.
-#
-# There are two kinds of commands:
-#
-# COMMANDS:
-#
-# They are output into `config.status' via a quoted here doc. These
-# commands are always associated to a tag which the user can use to
-# tell `config.status' what are the commands she wants to run.
-#
-# INIT-CMDS:
-#
-# They are output via an *unquoted* here-doc. As a consequence $var
-# will be output as the value of VAR. This is typically used by
-# `configure' to give `config,.status' some variables it needs to run
-# the COMMANDS. At the difference of `COMMANDS', the INIT-CMDS are
-# always run.
-#
-#
-# Some uniformity exists around here, please respect it!
-#
-# A macro named AC_CONFIG_FOOS has three args: the `TAG...' (or
-# `FILE...' when it applies), the `COMMANDS' and the `INIT-CMDS'. It
-# first checks that TAG was not registered elsewhere thanks to
-# AC_CONFIG_UNIQUE. Then it registers `TAG...' in AC_LIST_FOOS, and for
-# each `TAG', a special line in AC_LIST_FOOS_COMMANDS which is used in
-# `config.status' like this:
-#
-# case $ac_tag in
-# AC_LIST_FOOS_COMMANDS
-# esac
-#
-# Finally, the `INIT-CMDS' are dumped into a special diversion, via
-# `_AC_CONFIG_COMMANDS_INIT'. While `COMMANDS' are output once per TAG,
-# `INIT-CMDS' are dumped only once per call to AC_CONFIG_FOOS.
-#
-# It also leave the TAG in the shell variable ac_config_foo which contains
-# those which will actually be executed. In other words:
-#
-# if false; then
-# AC_CONFIG_FOOS(bar, [touch bar])
-# fi
-#
-# will not create bar.
-#
-# AC_CONFIG_FOOS can be called several times (with different TAGs of
-# course).
-#
-# Because these macros should not output anything, there should be `dnl'
-# everywhere. A pain my friend, a pain. So instead in each macro we
-# divert(-1) and restore the diversion at the end.
-#
-#
-# Honorable members of this family are AC_CONFIG_FILES,
-# AC_CONFIG_HEADERS, AC_CONFIG_LINKS and AC_CONFIG_COMMANDS. Bad boys
-# are AC_LINK_FILES, AC_OUTPUT_COMMANDS and AC_OUTPUT when used with
-# arguments. False members are AC_CONFIG_SRCDIR, AC_CONFIG_SUBDIRS
-# and AC_CONFIG_AUX_DIR. Cousins are AC_CONFIG_COMMANDS_PRE and
-# AC_CONFIG_COMMANDS_POST.

-# If DEST is member of LIST, expand to ACTION-IF-TRUE, else ACTION-IF-FALSE.
-#
-# LIST is an AC_CONFIG list, i.e., a list of DEST[:SOURCE], separated
-# with spaces.
-#
-# FIXME: This macro is badly designed, but I'm not guilty: m4 is. There
-# is just no way to simply compare two strings in m4, but to use pattern
-# matching. The big problem is then that the active characters should
-# be quoted. Currently `+*.' are quoted.

-# The code produced used to be extremely costly: there are was a

-# `#undef' templates with trailing space, and `#undef' templates
-# without trailing spaces. The full script was run on each of the m
-# lines of `config.h.in', i.e., about n x m.
-#
-# Now there are two scripts: `conftest.defines' for the `#define'
-# templates, and `conftest.undef' for the `#undef' templates.
-#
-# Optimization 1. It is incredibly costly to run two `#undef'
-# scripts, so just remove trailing spaces first. Removes about a
-# third of the cost.
-#
-# Optimization 2. Since `#define' are rare and obsoleted,
-# `conftest.defines' is built and run only if grep says there are
-# `#define'. Improves by at least a factor 2, since in addition we
-# avoid the cost of *producing* the sed script.
-#
-# Optimization 3. In each script, first check that the current input
-# line is a template. This avoids running the full sed script on
-# empty lines and comments (divides the cost by about 3 since each
-# template chunk is typically a comment, a template, an empty line).
-#
-# Optimization 4. Once a substitution performed, since there can be
-# only one per line, immediately restart the script on the next input
-# line (using the `t' sed instruction). Divides by about 2.
-# *Note:* In the case of the AC_SUBST sed script (_AC_OUTPUT_FILES)

+# This files handles about all the preparation aspects for
+# `config.status': registering the configuration files, the headers,
+# the links, and the commands `config.status' will run. There is a
+# little mixture though of things actually handled by `configure',
+# such as running the `configure' in the sub directories. Minor
+# detail.
+#
+# There are two kinds of commands:
+#
+# COMMANDS:
+#
+# They are output into `config.status' via a quoted here doc. These
+# commands are always associated to a tag which the user can use to
+# tell `config.status' what are the commands she wants to run.
+#
+# INIT-CMDS:
+#
+# They are output via an *unquoted* here-doc. As a consequence $var
+# will be output as the value of VAR. This is typically used by
+# `configure' to give `config,.status' some variables it needs to run
+# the COMMANDS. At the difference of `COMMANDS', the INIT-CMDS are
+# always run.
+#
+#
+# Some uniformity exists around here, please respect it!
+#
+# A macro named AC_CONFIG_FOOS has three args: the `TAG...' (or
+# `FILE...' when it applies), the `COMMANDS' and the `INIT-CMDS'. It
+# first checks that TAG was not registered elsewhere thanks to
+# AC_CONFIG_UNIQUE. Then it registers `TAG...' in AC_LIST_FOOS, and for
+# each `TAG', a special line in AC_LIST_FOOS_COMMANDS which is used in
+# `config.status' like this:
+#
+# case $ac_tag in
+# AC_LIST_FOOS_COMMANDS
+# esac
+#
+# Finally, the `INIT-CMDS' are dumped into a special diversion, via
+# `_AC_CONFIG_COMMANDS_INIT'. While `COMMANDS' are output once per TAG,
+# `INIT-CMDS' are dumped only once per call to AC_CONFIG_FOOS.
+#
+# It also leave the TAG in the shell variable ac_config_foo which contains
+# those which will actually be executed. In other words:
+#
+# if false; then
+# AC_CONFIG_FOOS(bar, [touch bar])
+# fi
+#
+# will not create bar.
+#
+# AC_CONFIG_FOOS can be called several times (with different TAGs of
+# course).
+#
+# Because these macros should not output anything, there should be `dnl'
+# everywhere. A pain my friend, a pain. So instead in each macro we
+# divert(-1) and restore the diversion at the end.
+#
+#
+# Honorable members of this family are AC_CONFIG_FILES,
+# AC_CONFIG_HEADERS, AC_CONFIG_LINKS and AC_CONFIG_COMMANDS. Bad boys
+# are AC_LINK_FILES, AC_OUTPUT_COMMANDS and AC_OUTPUT when used with
+# arguments. False members are AC_CONFIG_SRCDIR, AC_CONFIG_SUBDIRS
+# and AC_CONFIG_AUX_DIR. Cousins are AC_CONFIG_COMMANDS_PRE and

+# The code produced used to be extremely costly: there are was a

+# `#undef' templates with trailing space, and `#undef' templates
+# without trailing spaces. The full script was run on each of the m
+# lines of `config.h.in', i.e., about n x m.
+#
+# Now there are two scripts: `conftest.defines' for the `#define'
+# templates, and `conftest.undef' for the `#undef' templates.
+#
+# Optimization 1. It is incredibly costly to run two `#undef'
+# scripts, so just remove trailing spaces first. Removes about a
+# third of the cost.
+#
+# Optimization 2. Since `#define' are rare and obsoleted,
+# `conftest.defines' is built and run only if grep says there are
+# `#define'. Improves by at least a factor 2, since in addition we
+# avoid the cost of *producing* the sed script.
+#
+# Optimization 3. In each script, first check that the current input
+# line is a template. This avoids running the full sed script on
+# empty lines and comments (divides the cost by about 3 since each
+# template chunk is typically a comment, a template, an empty line).
+#
+# Optimization 4. Once a substitution performed, since there can be
+# only one per line, immediately restart the script on the next input
+# line (using the `t' sed instruction). Divides by about 2.
+# *Note:* In the case of the AC_SUBST sed script (_AC_OUTPUT_FILES)
+# this optimization cannot be applied as is, because there can be
