/bin/kill is broken! (was Re: SIGPWR)

Aaargh! (or, I just tried to figure it out...) It seems that there is
some confusion about which signals do what on the sparc. bash does not
list a PWR signal, /bin/kill does. So I tried /bin/kill -PWR to see what
signal I got:

susan# /bin/kill -PWR $!
[1]+  User defined signal 1   ./strace sleep 300

Hmm, USR1 is 30 according to bash & signal.h. Lets try /bin/kill -USR1:

susan# /bin/kill -USR1 $!  
[1]+  Bus error               ./strace sleep 300

It would seem that /bin/kill is sending signals according to i386 signal
numbers... From what I can gather, sparc doesn't really have a PWR signal
at the moment, Solaris (and presumably SunOS) use 19 (which is SIGCONT for
us). This may be somthing to ask on the sparclinux list...
