Looking for a make version to better support software versions

[Wm E. Davidsen Jr]

  You can sort of do this now. You can put the defines in a separate
header file and have your main header file include them, setting
dependencies for each source which must change, or you can make a dummy
item which you touch when you change the define, then make objects
depend on it.

  None of this is automatic, but it is portable.

	# these change when OS is redefined
	OSLIST	= part2.o random.o report3.o

	# touch osdef.inc when the OS define is changed
	$(OSLIST):: osdef.inc

  I think a portable program to go through files and generate some list
of defines used would be more useful to you and others.
