I have sent my patches for make to build on MinGW/MSYS to the maintainer (Paul
Smith) for inclusion in the next version 3.81. As 3.80 is still in rc phase,
they haven't been included in CVS yet. For those of you who can't wait,
attached is a patch against 3.80rc2. Run with patch -p0 and run autoheader,
autoconf and automake after (mine aren't the correct versions and lack certain
macros). It should then build with configure && make. Note that the tests
don't yet work by default, and an attempt to run make check will delete some of
them. Just run tests/run/make_tests instead (some fail).
