Thanks for the report.  Failures in test 79 and 82 are already well-reported 
and fixed in CVS.  I'm focusing on the other thing you turned up:

This was a testsuite bug, for assuming that kill -1 reliably kills shells with 
signal 1 (as a counterexample, ksh traps SIGHUP and exits normally with status 
127), but I've already tried to improve things in CVS.  So far, I have not 
found any counter-case for signal 13 reliably killing a shell.  What does this 
output for you, with m4 1.4.5?

$ echo 'syscmd(kill -13 $$)sysval' | m4
