Could come in handy sometimes, perhaps, but maybe there are other ways?
If it is the size of the resulting executables that prevents you from
linking each main.o file with all the other .o files (except the main ones),
couldn't you just put all the non-main .o files into an archive and then let
the linker figure out what to link against what for you? Make has pretty
much all rules for building archives in a good way built in, so this is
easy to do.
If it's mainly a matter of avoiding clashes between the different Main
modules, it should, with a little bit of care, not be too hard to structure
the makefile to deal with that.
