Win32, compiles, under, MinGW/Msys!

I have now been able to compile the backend using the Mingw/Msys
environment under Windows XP! I used the PeerDirect Win32 patch, and
SRA's patch. The MinGW environment is very easy to use and powerful.
It has gmake, bash, sed, and gcc, among other things.

It doesn't link because I am missing some functions, but it runs
configure and compiles with warnings. Output at:

http://momjian.postgresql.org/cgi-bin/pgpatches/win32.log

My two big remaining items are fork/exec, which Jan should complete
this week, and signals. I will ask Jan for help on this too.

The changes are minimal, about a 2k diff. I will post the patch to
patches once I review it.
