If it's in /usr/local/bin, then it either isn't an appropriate MSYS build, or it isn't correctly installed; it *should* be an MSYS special binary, in /bin. Have you installed the MSYS supplementary tools? (These were formerly bundled as msysDTK). If yes, what version? For recent autoconf, the m4-1.4 from the old msysDTK probably isn't sufficient; you should use the newer m4-1.4.7, from the supplementary tools collection on the MinGW SF download page.
