If nothing else, could STACK_BOUNDARY be changed to 64 on glibc2
systems where the startup does seem to do double alignment, thus 32 is
presumably incorrect?  That will sort out the problem for G77 on GNU
systems using libc2.

Making it 64, dependent on -malign-double, would solve the problem for
us on other GNU/Linux with a patched crt or on other systems which do
double-align the stack.  I'd meant to try to find out what stack
alignment DJGPP and BSD provide but haven't done so.
