Hmm, which compilers do this?  Let's not forget that the normal aproach when
compiling C/C++ is to compile the source files one at a time in isolation.  In
those circumstances, you can't inline much at all, even if your compiler would
be willing to do so.

???? You can't inline stuff you don't have available unless you're psychic.
