When is a compller needed in testing

[Arthur Schwarz]

15.2.3 Parallel Test Harness
The example given in this section:

    TESTS = foo.pl bar.py baz
    TEST_EXTENSIONS = .pl .py
    PL_LOG_COMPILER = $(PERL)
    AM_PL_LOG_FLAGS = -w
    PY_LOG_COMPILER = $(PYTHON)
    AM_PY_LOG_FLAGS = -v
    LOG_COMPILER = ./wrapper-script
    AM_LOG_FLAGS = -d
 
Shows specific identification of compilers, sic. PL_LOG_COMPILER and
PY_LOG_COMPILER. Automake seems to have knowledge of particular language
compilers and the user can specify their use as in:

    check_JAVA
    check_LISP
    check_PYTHON

For _JAVA, _LISP, _PYTHON can I use check_ or must I separately specify a
compiler as in ext_LOG_COMPILER and not use check_?

And just as a nit-noy, the document is clear to say that an AM_ prefix means
that the variable is available to the developer and if AM_ is missing then
the variable is available to the user. Why aren't ext_LOG_COMPILER prefixed
with AM_ext_LOG_COMPILER as is done with AM_ext_LOG_FLAGS?

Maintenance turns design into chaos
