Added MINGW32 changes.

This commits a number of changes from Earnie Boyd that allows GNU make
to build for MINGW32 systems.  Only missing from this commit are the
changes to configure.in etc.; I'm waiting for Earnie to sign papers for
those new files.

Also not here is any README.mingw32 etc. which would explain how to use
this port.
