Lionel Sambuc 84d9c625bf Synchronize on NetBSD-CVS (2013/12/1 12:00:00 UTC)
- Fix for possible unset uid/gid in toproto
 - Fix for default mtree style
 - Update libelf
 - Importing libexecinfo
 - Resynchronize GCC, mpc, gmp, mpfr
 - build.sh: Replace params with show-params.
     This has been done as the make target has been renamed in the same
     way, while a new target named params has been added. This new
     target generates a file containing all the parameters, instead of
     printing it on the console.
 - Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
     get getservbyport() out of the inner loop

# Note: The atomic operations here in these assembly files are atomic
# only with respect to regular memory on uniprocessor systems. Since
# we don't support any MP m68k systems, this is just fine. If we ever
# do, then these routines will probably need to be replaced with CAS-
# based routines (CAS generates an atomic bus cycle, whereas these
# others are merely single-instruction).
