egcs core-dumping on uthread_autoinit.c

[Marc Espie <Marc.Espie@liafa.jussieu.fr>]

If this happens to you, this is a known linker problem... the cc1 you have
was linked in a weird way.

Initially, I made cc1 link against static /usr/lib/libiberty.a to avoid this
problem, but this was cutting things too close, and the bug reappeared,
probably thanks to unrelated changes in libc or elsewhere...

The tree has been patched with a work-around in

src/gnu/egcs/f/lang-options.h

make sure you have the kludged version of that file (at least rev 1.2),
recompile and reinstall cc1, the problem should go away.

What's going on is that the 386 linker gets something wrong because of
the huge strings array in toplev.c, and something gets mislinked, so
that
void f(void) __attribute((constructor)) {}
kills cc1.

As a work-around, I've killed Fortran options help texts, until someone finds
where the linker errs.
