Re: RESOLVED: GCC 2.95.2 make problems under Cygwin 1.1.4


You need to find one of the cygwin mirror sites which has the source
tarballs alongside the binaries which setup downloads.  gcc-2.95.2 is one of
those which is significantly different from the standard gnu version.
binutils likewise.  Apparently, if you modify binutils/bfd, you must rebuild
the gcc as well, or g++ libraries will break.
