Problem 2: it appears that “make depends” and “make depend” have been
broken since:

which replaced support/mkdep with a version that lacked the “-c compiler”
option and the “--” end-of-options marker, both of which are required for
the “depends” make target:

$(Program) $(SUPPORT_SRC)mkdep* -c ${CC} -- *${CCFLAGS} ${CSOURCES}

If you want to use it, I'll fix it up.

PS: It seems like that Makefile line should use “sh” rather than
“$(Program)”, otherwise it would be impossible to go “make depend” before
the initial build.

The dependencies already in the Makefile are assumed to be correct, plus
you're making everything the first time through anyway. But it doesn't
really matter.

PPS: "mkdep" seems like a deficient exemplar of a robust shell script; lack
of quoting; broken and missing error checking; error messages to stdout
instead of stderr.

The BSDs still use it.
