This patch fixes a bug introduced by the patch for PR 13158, which only
shows up when -fno-omit-frame-pointer is used.  This option is useless
for IA-64, but some people insist on using it, so we need to make it
work.  The problem here is that we assume there is no frame pointer if
the frame size is zero, but this isn't true when -fno-omit-frame-pointer
is used, so we need to check for that also.

Mark, I'd like to install this patch and the patch for PR 13158 on the gcc-3.4 release branch.

That's fine; we're open for general bug fixing again now.

Thanks,
