Significantly shorten the Win32 build and shrink symbol tables
  for precompiled headers and debugging by eliminating large chunks
  of the windows.h declarations, especially the graphical user
  interface declarations.

  Also eliminates redundant inclusion of winsock and windows headers.
  As the GUI sections can be included by adding the windows.h include
  prior to any apr headers, these includes now imply something
  completely different.
