Did you put it in the toplevel or in
libgfortran/  I suspect it needs to be in the former,
because the latter probably shares the same config.cache and thus it
won't be checked a second time when running configure for libgfortran.

In any case, I think efforts would be better spent helping get a modern
libtool into the tree, since the one there now is ancient and I wouldn't
be surprised if the mingw/cygwin-specific parts have bitrotted from
years of neglect.  For example, this AC_LIBTOOL_WIN32_DLL macro was
removed/deprecated from libtool three years ago.
