Hello bug-autoconf readers, when I try to run Cygwin's /usr/bin/autoconf (2.63) on the git Autoconf tree, I get approximately \infty many instances of this warning:
| /usr/bin/m4:configure.ac:23: Warning: m4_eval: bad expression (bad input): + _m4_bmatch_( That's not good. git Autoconf should be bootstrappable with the latest (and ideally also several prior!) released Autoconf. I haven't had a chance to analyze this yet. Cheers, Ralf
