Thanks. Please resubmit with the new functions moved to right before
func_mode_link (or func_mode_install/func_mode_execute, in case you
intend to use them from inside them in a followup patch); there's a real
performance benefit to doing this for compile mode, as it saves the
shell from having to parse the functions in that case. It may be lost
in the fork/exec overhead on w32, but on GNU/Linux, libtool compile mode
overhead is dominated by shell parsing (see the 2007-02-11 changes for a
30% execution time reduction this way).
Done. Testing is still in progress (again, in conjunction with updated
argz.m4 patch). However, mdemo works (on all six test variants
described in the argz.m4 messages), and the entire "old" test suite
passes on cygwin(broken argz kernel: 1.5.24-2).
Also, please use round parentheses as per GCS for referring to functions
in the ChangeLog entry. I'll apply the reposted patch then.
Done.

* libltdl/config/ltmain.m4sh (func_mode_link): move wrapper
script generation from here...
(func_emit_libtool_wrapper_script): to this new function, and
write to stdout
(func_mode_link): move cwrapper source code generation from
here...
(func_emit_libtool_cwrapperexe_source): to this new function,
and write to stdout
(func_mode_link): call the two new functions and redirect
output to appropriate file.
