* gccspec.c (lang_specific_driver): Do nothing when NEXT_OBJC_RUNTIME
is declared.
* config/darwin.h (REAL_LIBGCC_SPEC): When -fgnu-runtime is
passed, use shared libgcc.

I should mention that with the GNU runtime, we want the shared libgcc for
exceptions so any patch that breaks the GNU runtime linking with the shared
libgcc should be rejected.

The change to gccspec.c was made by Franz Sirl on 2001-06-16, revision 43421. 
The mail on gcc-patches is at
.  There's further
discussion at .  I
think it's relying on the property that the GNU runtime is (always?) linked
with the dynamic libgcc.

This is because gccspec.c is adding -shared-libgcc when it sees an Objective-C
file, but inconsistently; it doesn't handle -x options, it doesn't handle the
-objC flag.  On Darwin, it's wrong to add -shared-libgcc like this because the
objective-C runtime uses setjmp/longjmp exceptions and some versions of Darwin
don't have a shared libgcc to use.
