#1 minorGems cross-compilation patch

[Geoff Kassel]

This is a (very minor) patch to allow cross-compilation
of minorGems on Linux for Win32-based platforms -
really just a case change for the included Winsock
header, from 'Winsock.h' to 'winsock.h'.

With this patch, the minorGems code used by MUTE
compiles and links correctly under XMinGW, and produces
a fully functional MUTE application.

(Sorry about the misfiling under feature requests -
there doesn't seem to be a patch tracker for this
project yet, and this seemed more appropriate than a
bug report.)
