The bsd signal names are out-of-order compared to the minix ones.
I found out (the hard way) that the (MINIX-descending) ordered list of
signals in <sys/signal.h> does not match the (BSD-descending) ordered
list of signals in usr/src/lib/libc/nbsd_libc/gen/sig{name,list}.c
Beyond being unfortunate, it prevents the trap command of ash to handle
correctly a named signal; a funny test case is
#!/bin/sh
trap 'echo trapping signal BUS' BUS
trap 'echo trapping signal 10 (USR1)' 10
trap # show me what is currently trapped
As a quick workaround, I disabled the use of the libc-provided
sys_sig{name,list} arrays for ash, and reverted to the hand-made array
which is used by the less capable MINIX libc. It allowed me to use
pkgsrc.
