# the name/ctxt numbers are very internals-dependent and thus
# change relatively frequently, and testing for their exact values
# them will fail annoyingly, so we just check their positions
# (using a non-constant replacement like this will make it less
# likely the compiler matches whatever other dummy value we
# choose).

# (These need to be out-of-place because OSX/BSD & GNU sed
# differ.)
