+Subject: [PATCH] kernel32: Add stub implementation of
+ EnumSystemFirmwareTables.
+
+A recent change to the game Everquest adds a call to EnumSystemFirmwareTables.
+This of course causes the game to crash. Adding this stub call restores full
+functionality to the game.

+Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=47523
