+# 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
