In file included from util/misc.c:36:0:
./include/grub/emu/misc.h:56:1: error: 'libintl_printf' is an unrecognized format function type [-Werror=format=]
 char * EXPORT_FUNC(xasprintf) (const char *fmt, ...) __attribute__ ((format (printf, 1, 2))) WARN_UNUSED_RESULT;

./include/grub/emu/misc.h:58:1: error: 'libintl_printf' is an unrecognized format function type [-Werror=format=]

The reason is libintl.h which redefines printf as libintl_printf. The problem
is not present in native mingw build which avoids redefinition.  Use
(format (__printf__) instead which is valid replacement in GCC.
