C++ automatic template instantiation?

One problem is that there is a number of things that should work but
don't, eg. producing libraries is difficult, and compiling with -S is
not supported (as well as producing an executable directly from
sources).

The other (IMO more important) problem is that it will be always
possible to trick the -frepo mechanism. For example, I believe
recompilation currently does not take the GCC_EXEC_PREFIX variable
into account (or any other environment variable). Also, never move any
files around between compilation and linking, or recompilation won't
find the original ones, anymore.
