With all the SysV/BSD hybrids out there, one cannot assume anything
about the values of the SIG* macros. Another problem is that
sys_siglist isn't available on many systems.
This program generates a file that defines the BSD-style sys_siglist
array and a signal_names array.
It is easy to add more exotic signals.
