What if you read in a function with the same signature? Will it just
replace it?

Can I add submit a patch to do something like this  (if it doesn't
disturb the makefile system that much)?

Maybe if one is building a library and sets a "LINK_IN_LIBS" flag or
something? I am guessing there might be other people that want
something like this - ie, anybody building a shared library that they
want to use in another application.
