Which situation exactly? After 'make mixclean'? 'copymix' is intended
to be run once to create complete source code, which cannot be later 
updated of course. And I prefer to keep this target, because to install
full 5.0 source if I want to compile 5.7 on iPaq, is realy impractical.

This simplifies Makefiles of most modules and libs, I don't see 
as a problem to create list of objects authomaticaly if it is
possible (and in 95% it is). The problem is to create more modules using
one rule. It is possible to specify (at least GNU make) target specific variables:

default: cmd1 cmd2

cmd1: CMD_OBJS = maina.o
cmd1: PGM = testa
cmd1: cmd

cmd2 : PGM = testb
cmd2 : CMD_OBJ =mainb.o
cmd2 : cmd

but I don't know how to change this:

cmd: bincmd

ARCH_CMD_OBJS := $(foreach obj,$(CMD_OBJS),OBJ.$(ARCH)/$(obj))

bincmd: $(ARCH_INTER_OBJS) $(DEPENDENCIES)
        $(CC) $(LDFLAGS) $(XTRA_LDFLAGS) -o $@ $(ARCH_INTER_OBJS) $(LIBES) $(MATHLIB) $(XDRLIB)

to create properly list of objects and objects.
