--- Comment #3 from Ian Lance Taylor <ian at airs dot com> ---
Unfortunately that patch breaks the build on x86 GNU/Linux.  The problem is
that the split-stack support (the __morestack symbol) must be linked into the
shared library directly, not via -lgcc_s.  So it's necessary to link with -lgcc
also.  The correct link on x86 GNU/Linux is -lgcc -lgcc_s, but using
-shared-libgcc only links with -lgcc_s.

I think -lgcc -lgcc_s should also work on x86 Solaris, as the problematic
symbol is in -lgcc_eh,  not -lgcc.  But I'm not sure about the best way to get
that, as not all systems support -lgcc_s.
