After the latest COMPAT_OLDSOCK messup I took the time to
grep through the kernel sources to find uses of "compat"
options without the "opt_*.h" includes and vice versa.
So I stepped onto the SA_USERTRAMP signal flag which is
only set in compat/sunos/sunos_misc.c but never used
because the signal delivery code in m68k/sunos_machdep.c
knows for itself how to deliver signals.

Is there a reason to leave it in the code?

best regards
