Hi,

when building the winsup tree from scratch, I'm getting a link error
in winsup/mingw when trying to build mingwthrd_dummy.exe:

/usr/lib/gcc-lib/i686-pc-mingw32/3.2/../../../../i686-pc-mingw32/bin/ld: cannot find -lmingwex

As it turns out, the Makefile builds mingwthrd_dummy.exe *before* building
in the subdirs, including mingwex.  Even when changing that, it still doesn't
build since there's no -L directive which adds the mingwex subdir to the
linker paths.

As a (clumsy) patch I used this to heal the problem locally:

Perhaps one of the Mingw guys takes a look?  Or should I just check that
patch in?
