# This could probably be merged with ../cc_int/Makefile, but bsd.lib.mk
# is such a !@#!*#% nightmare because of how it reprograms the dependencies,
# suffix rules, SRCS, etc.  It's easiest to cheat by using bsd.prog.mk and
# SRCS to get dependencies.

# ../Makefile.inc will put an absolute path to our objdir in CFLAGS.
# Prevent mkdep from using it, so that we don't have to give rules for
# aliases of generated headers.
