Changes to buildsystem patchset

Implemented changes to the buildsystem patchset suggested by jamesyonan in IRC
meeting on 17th Feb 2010:

1) Remove variables added to version.m4 and use win/settings.in instead
2) Add ENABLE_<FEATURE> configuration to win/settings.in instead of parsing
   config-win32.h for them

This patch applies on top of the previous 13 patches.
