core dumps on signals

So the library is supposed to define signal names (and forget libc 5)...
Which signal is supposed to be SIGSYS? Neither of the two junk signals
dump core, so they can not be substituted without kernel changes.

(only 4 of 8 ports have this problem: i386, arm, m68k, ppc)

Name Unix98 Linux

ABRT core core
FPE core core

ALRM exit exit
HUP exit exit
INT exit exit
KILL exit exit
PIPE exit exit
POLL exit exit
PROF exit exit
TERM exit exit
USR1 exit exit
USR2 exit exit
VTALRM exit exit
PWR n/a exit (normal systems would ignore by default)
STKFLT n/a exit (this is Linux-specific junk)
UNUSED n/a exit (this is Linux-specific junk)
WINCH n/a ignore
CHLD ignore ignore
URG ignore ignore
TSTP stop ignore if daemon, otherwise exit
TTIN stop ignore if daemon, otherwise exit
TTOU stop ignore if daemon, otherwise exit
STOP stop stop
CONT unstop unstop
EMT n/a n/a (normal systems would core by default)
