I took your suggestion, and it's worked out pretty well so far.

I did not quite understand how to add my own system header paths to the 
hard-coded paths in clang/lib/Frontend/InitHeaderSearch.cpp (my attempt 
failed to solve the problem), so I ended up having to create a link from 
/usr/include/stdarg.h to 
/usr/lib/gcc/i686-apple-darwin9/4.0.1/include/stdarg.h so that 
<iostream> would compile.

In my latest small project (51 headers, 14 sources so far), Clang was 
able to compile every source, some of which included templates, except 
for the ones that instantiated 
boost::uuids::string_generator::operator() (Boost.Uuid is a new library 
in version 1.42). However, GCC was able to compile those sources and 
successfully link the resulting objects with the Clang-built objects.

Knowing where Clang has come from, I am impressed with the progress! I'm 
looking forward to the day I can completely switch over. :)
