I don't use msys.  I build from a cygwin environment, with a
few shell scripts wrapping mingw32-gcc/mingw32-g++ that
simply call cygpath on absolute paths (-I, -L, sources,
outputs, etc).

I built with:
   $ ../src/configure --build=mingw32 --host=mingw32 --target=mingw32

TUI is disabled automatically, since there's no curses, and I don't
have the gdbtk here.

You have DLL support disabled.  If you rebuild the mingw gdb
with libexpat available, you'll get as good
backtrace information.

I see it here too.  More comments in the next email.
