[PATCH 3/8] xfree86: allow modules to be built without undefined symbols
Yaakov (Cygwin/X)
yselkowitz at users.sourceforge.net
Thu Mar 29 01:22:36 PDT 2012
From: Yaakov Selkowitz <yselkowitz at users.sourceforge.net>
This will be necessary to port Xorg to Cygwin, but other platforms may
find this useful as well.
