There were other problems with the last version I saw: it used #ifdef
__linux__ unnecessarily, and it introduced a new, undocumented, ABI.
These problems are correctable if you or somebody wants to sort them
out.

On the other hand, as I've said before, there is no earthly reason to
use dlopen here.  It would be entirely appropriate to invoke a filter
program which would be provided by the compiler.  That option would
always work, with fewer ABI issues.

In fact, that very program already exists: it's the program you get by
compiling cplus-dem.c with MAIN defined.  So I think that what we
really need is an option to the linker which tells it which demangling
program to run.
