Shared libobjc in gcc 3.0.2 doesn't work with "make check"

Shared libobjc in gcc 3.0.2 doesn't work with "make check"

[H . J . Lu]

The ObjC testcase doesn't work at all unless there is libgcc_s.so.1
somewhere available for dynamic linker. It is because the shared
libobjc has libgcc_s.so.1 in DT_NEEDED and the GNU linker treats
it just like dynamic linker. That means ld won't search -L for
libgcc_s.so.1. If there is no libgcc_s.so.1 for dynamic linker,
which happens when you never install gcc 3.x before, all ObjC tests
will fail. For ObjC test, you should use LD_LIBRARY_PATH Or -rpath
for the final link.

AFAIR this was fixed in the mainline by:

2001-06-16  Franz Sirl  <Franz.Sirl-kernel@lauterbach.com>

         * gccspec.c (lang_specific_driver): If compiling ObjC, add
         -shared-libgcc when necessary.
         * Makefile.in (gccspec.o): Compile with DRIVER_DEFINES.

Hmm, totally forgot about that, it should have gone into 3.0.1 already...

Franz.

Why not backport it to 3.0.x?

As I said I forgot about it and now it's too late for 3.0.2. I'll put it in 
my queue for 3.0.3.
