This is fine in the short term, but I don't think this will work in  
general.  Consider if you have:

somevarargsfunction(1, 2, NULL);

This will pass as an int, instead of as a pointer.  This matters on 64- 
bit targets.

GCC has a strange __null extension that it uses for C++ mode, should  
we add support for it?
