+commit 2632c008e2c2cd61fefb622ed671ea3e6bd2e2a6

+Date: Tue Jul 21 22:59:36 2009 -0400
+
+ autoconf.mk: include before config.mk for top level files
+
+ By including autoconf.mk before config.mk, all top level files can use any
+ config options it sets up (like <arch>_config.mk) or the Makefile itself
+ without being forced to use lazy evaluation.

+ Remove static declaration from gunzip_bmp()
+
+ This patch removes the static declaration from gunzip_bmp()
+
+ Without it, the gunzip_bmp() function is not visible to
+ common/lcd.c and fails to compile with an error.

+ unify HOST_CFLAGS and HOSTCFLAGS
+
+ The top build system sets up HOSTCFLAGS a bit and exports it, but other
+ places use HOST_CFLAGS instead. Unify the two as HOSTCFLAGS so that the
+ values stay in sync.
