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

# IP/MPLS & LDP label reallocation test
# Create 4 routers connected like this: R1--R2--R3--R4--
# The goal is to push packets from R1 to the R4 shmif1 (the right one) interface
# Enable MPLS forwarding on R2
# Disable IP forwarding and enable MPLS forwarding on R3
# Start ldpd and wait for adjancencies to come up
# Add an alias on shmif1 on R4 for which we already have a route on R3
# Now: * R4 should install label IMPLNULL for that prefix
# * R3 should realloc the target label from IMPLNULL to something else
