Which compiler(s) are you using exactly?  Which version(s)?  More
importantly, which version of libtool are you using?  Have you changed
that too recently?

Two small pieces of advice:

 1. When declaring PROGRAMS, you don't need to add the `$(EXEEXT)'
    suffix explicitly to them: automake will automatically do that
    for you; for more info, see:
     <http://www.gnu.org/software/automake/manual/html_node/EXEEXT.html>

 2. When declaring stuff used by the testsuite and that should build
    by "make check", you can typically use the `check_' prefix, e.g.:
      check_PROGRAMS = test_main G72x/g72x_test
      check_LTLIBRARIES = GSM610/libgsm.la
    If you do that, you won't need to declare the dependency of `check'
    from $(noinst_PROGRAMS).

I'm not able to reproduce your problem with either my native GCC or my
Linux->MinGW cross compiler (kindly offered by official Debian packages).
And reading the above, I suspect it *might* be a libtool bug.

Could you please provide your libtool and compiler versions, the `ltmain.sh'
file installed by libtoolize, the `Makefile.in' generated by automake, the
`config.log' generated by configure, the relevant output of configure and
make, and the list of files generated in `G72x/.libs' (and everything else
you think could be useful)?

Thanks,
