Those were present in older versions of gcc, but not anymore. The following patch fixes the problem (while also breaking backwards compatibility): diff -ur grub2-1.95+20071101/include/grub/powerpc/libgcc.h grub2-1.95+20071101.new/include/grub/powerpc/libgcc.h --- grub2-1.95+20071101/include/grub/powerpc/libgcc.h 2007-07-21 23:32:24.000000000 +0000 +++ grub2-1.95+20071101.new/include/grub/powerpc/libgcc.h 2007-12-26 08:42:49.000000000 +0000 @@ -26,19 +26,12 @@ void EXPORT_FUNC (__floatsidf) (void); void EXPORT_FUNC (__floatsisf) (void); void EXPORT_FUNC (__lshrdi3) (void); -void EXPORT_FUNC (__make_dp) (void); -void EXPORT_FUNC (__make_fp) (void); void EXPORT_FUNC (__muldf3) (void); void EXPORT_FUNC (__mulsf3) (void); -void EXPORT_FUNC (__pack_d) (void); -void EXPORT_FUNC (__pack_f) (void); void EXPORT_FUNC (__subdf3) (void); void EXPORT_FUNC (__subsf3) (void); -void EXPORT_FUNC (__thenan_df) (void); -void EXPORT_FUNC (__thenan_sf) (void); void EXPORT_FUNC (__trampoline_setup) (void); void EXPORT_FUNC (__truncdfsf2) (void); -void EXPORT_FUNC (__unpack_d) (void); -void EXPORT_FUNC (__unpack_f) (void); void EXPORT_FUNC (__floatdisf) (void); +void EXPORT_FUNC (__floatundisf) (void); void EXPORT_FUNC (__cmpdi2) (void); Is there any way we can preserve compatibility with gcc 3.x ?
