Hi Peter,
Now, since ghc -M does such a great job at gobbling up the dependencies, I wonder if it was not possible to extend its functionality a little bit so that it also determines the .o files that are required to link a Main program. I could imagine something like an -optdep-Main and then the program name.
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.
