Replacing Honza's patch with yours fixes the failures for
gcc.c-torture/compile/990517-1.c for "-O2" and "-O3 -g" with no
additional failures in C, C++, F77 and ObjC tests.

Indeed, your patch fixes that particular mcore-elf failure.
(For the record: building fails much much later because
libstdc++-v3 is "unable to detect exception model" but that's a
totally different issue.)

Very well.  Not having a dreamcast, I find a simulator cheap
enough.  :-)
