RE: any "smart linking" efforts?

Thanks Eric.
The compiler / linker options suggested by 2) have a generous intent, but
they don't work with dynamic linking :(

Am I asking for an impossible to implement feature?
There seem to be linkers out there (for platforms that should remain
nameless) that are capable of garbage-collecting unused functions even when
the executable is dynamically linked against system libraries.

Also, the same linker can figure out when two functions are bitwise
identical (say two C++ template instantiations in different translation
units) and keep only one copy.
