Subject: [PATCH] fix include loop on MinGW due to libintl.h pulling stdio.h

                 from grub-core/lib/libgcrypt-grub/cipher/rfc2268.c:3:
./include/grub/list.h:34:18: warning: conflicting types for 'grub_list_push' [en
abled by default]

ist_push' was here

list.h needs just ATTRIBUTE_ERROR from misc.h; split compiler features
into separate file grub/compiler.h and include it instead.
