Not even to temporarily circumvent a known bug?
I understand your objection (multi-arch, if not general
distaste), but there are lots of ifdefs in infrun.c already...

FYI, I was thinking along the lines of
	(currently_stepping (ecs)
#ifdef TM_i386SOL2_H
	&& !(step_range_end
	    && INNER_THAN (read_sp (), (step_sp - 16)))
#endif
	));

which would preserve the behavior on x86 solaris, while
protecting the rest of the world until Peter can come up
with a better implementation.
