+From 7ef4a07165d49e671f6f569ee87bfe893b1e7fcf Mon Sep 17 00:00:00 2001

+Subject: [PATCH] Move initialization of server_support from
+ __glXProcessServerString to __glXCalcualteUsableExtensions. By having both
+ callers of __glXProcessServerString initialize the bit-fields passed in, we
+ guarantee that the correct amount of data is initialized:
+
+This fixes bugzilla #7353.
