Sure, clearly a straightforward dependency. ;-)

I think it should, though. __builtin

No can do. It had been there for too many releases (even one is
one too many), at least 13 years according to the ChangeLogs.

I've installed the following refined fix, after testing on i586-suse-linux and
sparc-sun-solaris2.10. Most
(allocate_dynamic_stack_space): Remove SETJMP_VIA_SAVE_AREA
support.
* function.c (instantiate_virtual_regs): Likewise.
* postreload-gcse.c (bb_has_well_behaved_predecessors): Return false
for a block with a single abnormal incoming edge.
* config/sparc
