Please ignore this patch. It's wrong (= instead of ==). I'll send a fixed version.

By moving the definition of GCC_ATTR and GCC_FMT_ATTR from audio_int.h to qemu-common.h these macros are now generally available for further patches which add the gcc format attribute. Newer gcc versions support format gnu_printf which is better suited for use in QEMU than format printf (QEMU always uses standard format strings (even with mingw32)).
