Side note, the GNU "equivalent" of MS lib.exe is ar. (ld corresponds to
MS link.exe).

Regarding the issue, it is a bad sign that the archives are named libmbmath.lib,
libmbutil.lib etc. For a Cygwin build, you want them named libmbmath.a. The
.lib suffix is a clear indicator of a problem earlier in the build, just
like Corinna said. Is the Cygwin binutils package installed properly? I
imagine something like this could happen if the binutils install is broken
and the Microsoft tools are on $PATH (but I haven't tested that).
