+Subject: [PATCH 1/2] mesa: use a prefix for the program lex
+
+This avoids us making a global yylex symbol which will interfere will
+all sorts of apps.
+
+with libdricore which can't do symbol visibility currently we pollute
+the namespace with this.
+
+This is a candidate for 9.0 & stable branches.
