Return to winmultiwindowclass.c CVS log

Up to [XFree86 CVS] / xc / programs / Xserver / hw / xwin

 161. Implement a major #include rework throughout the tree.  Also enforce it
      for all non-external builds (i.e. in-tree & SDK)  (Marc La France).
 160. Rework the building of hw/xfree86/parser to be more in line with the
      building of other server subdirectories (such as common/)
      (Marc La France).
 159. ANSIfy /xc/lib/font/builtins/, and fix warnings, whitespace & formatting
      (Marc La France).

Notes:
 - `make World` highly recommended ;-)
 - This will be further tested in the next few days.
