description:
C++ exceptions doesn't work in i386 shared libs when using sjlj exceptions
(as a.out does per default.)  This is because the compiler forgets to
restore the PIC register after a builtin_setjmp (i.e. when catching an
exception.)  This fix is taken from the gcc 2.95 branch.

Fixes PR#9110.
