Patches for building Wget with Mingw32

I have built Wget on Mingw32 using MSYS to run configure.
I had to manually edit the Makefiles and (since I have Emacs) am using the 
Info documentation.
The changes to the Makefile consisted of changing DEFS to "-DWINDOWS 
-DHAVE_CONFIG_H" and adding "-lwsock32" to LIBS.
Below is a unified diff of my changes to the code (I hope AOL doesn't mangle 
this.):
