Subject: [PATCH] fix Mingw W64-32 cross compile failure due to printf
39700a
 redefinition in libintl.h
39700a
39700a
In file included from util/misc.c:36:0:
39700a
./include/grub/emu/misc.h:56:1: error: 'libintl_printf' is an unrecognized format function type [-Werror=format=]
39700a
 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=]
39700a
39700a
The reason is libintl.h which redefines printf as libintl_printf. The problem
39700a
is not present in native MinGW build which avoids redefinition.  Use
39700a
(format (__printf__) instead which is valid replacement in GCC.
39700a
39700a
v2: add grub-core/lib/libgcrypt/src/g10lib.h
39700a
v3: modify g10lib.h during import
