I've seen this before.  You can't use a native (MinGW) build of m4 with 
autoconf, under MSYS.  The problem appears to be the result of CRLF 
line endings, which the natively built m4 emits; the stray CRs leave 
unexpected output, causing m4sugar to fail.

You need to use an MSYS special build of m4:
http://downloads.sourceforge.net/mingw/m4-1.4.7-MSYS.tar.bz2

or patch the m4 sources to avoid text mode I/O entirely, if you insist 
on building anything more recent as a MinGW build.

HTH,
Keith.
