Since the version of m4 that comes with Solaris likely works with all our .m4 files and there is no way to check the version (no --version, -v, -V, or anything from what I can tell) I guess we have no choice but to not check the m4 version.
flex on the other hand we can check. How about this for the new regex (for reference the old one is $version =~ m/\s([\d\w\.]+)$/m; -- matching a version at the end of the line): $version =~ m/\s([\d\.]+\w?)/m; It works with Apple's flex and still works with glibtoolize, autoconf, and automake.

I'm not a Perl person, so I wrote the example regular expression parser in sed. These commands were done on my Mac OS X 10.6 system. I have no idea where the apps came from. I know the sed, at least, does not recognize regular expressions documented for GNU sed (such as \< \> for begin/end word). Maybe it is a BSD sed? I was just trying to illustrate how to fix the broken parsing of Ralph's "flex --version". Assuming the RE parser I wrote is satisfactory, it would have to be adapted to fit in the framework, i.e., it has to be portable.
