Overloading vs. string functions, etc.

...at that time the config scripts can be hacked to switch from c_std to 
c, which just pass-through. That's the idea, at least. Some tweaking will 
probably be involved but it should be minimal.

Uli and I talked about this a bit ago, but I can't remember the resolution.
Basically it involves changing glibc's 

__BEGIN_DECLS

for c++ to be

namespace std
{
  extern "C"
  {

and similar changes to __END_DECLS

All in all, this is a simpler approach to solving this correctly than the 
contortions c_shadow does. The downside is that then the C++ headers 
aren't exactly correct either, as there is extra, non-standard gunk in 
the C++ headers (or could be, if things aren't done carefully.)

Note that both Sun and Microsoft use this approach, probably others.

I'm starting to lean towards it as the real solution for gnu-linux.

(throw specs are irrelevant to this as Jason's already got that covered.)
