One can check the arguments to make within make. You can have version.c
be a phony target only when the argument to make was not "program"
(warning: untested)
i.e. try something like
ifneq ($(MAKECMDGOALS),program)
.PHONY version.c
endif
This should cause version.c to be compiled every time except when
you do a make program. version.c will be recompiled even if no other
file needed to be recompiled.
