maintainer mode

[Andrew Tridgell]

How many people use the maintainer mode in the new Makefile? I'm
wondering if we can do without it.

The rule for creating object files is now:

.c.o: @MAINT@ .deps/.dummy
	@if (: >> $@ || : > $@) >/dev/null 2>&1; then rm -f $@; else \
	 dir=`echo $@ | sed 's,/[^/]*$$,,;s,^$$,.,'` $(MAKEDIR); fi
	@MAINT@@if (: >> .deps/$@ || : > .deps/$@) >/dev/null 2>&1; then :; \
	@MAINT@ else dir=.deps/`echo $@ | sed 's,/[^/]*$$,,;s,^$$,.,'` \
	@MAINT@      $(MAKEDIR); fi; rm -f .deps/$@ .deps/$@d
	@echo Compiling $*.c
	@$(CC) -I. -I$(srcdir) $(FLAGS) -c $< -o $@ \
	@MAINT@ -Wp,-MD,.deps/$@ && \
	@MAINT at sed 's|^'`echo $@ | sed 's,.*/,,'`':|$@:|' \
	@MAINT@  <.deps/$@ >.deps/$@d && \
	@MAINT at rm -f .deps/$@ && : >.deps/.stamp

that seems ridiculous. And right now it's broken and is dumping lots
of junk on the screen while compiling.

Maybe we should just go for a script called something like
script/compile and be done with it? Or if it isn't being used then
maybe we should get rid of it completely. I don't use it myself.

I like Makefiles to be readable. the Samba one is starting to resemble
line noise :-)
