+#      This script munges the native include files provided with Windows NT
+#      3.5 SDK systems so as to provide a reasonable namespace when
+#      compiling with gcc.  The header files by default do not
+#      provide many essential definitions and declarations if
+#      __STDC__ is 1.  This script modifies the header files to check
+#      for __STRICT_ANSI__ being defined instead.  However the most 
+#      important modification is to change all occurences of __stdcall
+#      and __cdecl to __attribute__((stdcall)) and __attribute__((cdecl)),
+#      respectively.  Once munged, the
+#      resulting new system include files are placed in a directory
+#      that GNU C will search *before* searching the /mstools/h
+#      directory.  This script should work properly for an /mstools/h
