Well, here we go :-)

The patch below is against Debian gccchecker 0.9.9.1-15
and basically consists of two parts:

Part 1
======
Mainly updates of the stubs, some generic fixes and
corrections to the build system.

Part 2
======
The c++ support files in the stubs/c++ directory.

Status
======
I've tested this successfully on a fairly complex program that 
uses RTTI, exceptions and the STL (but needs not get linked
against libstdc++).

The only problem I met is that during exception unwinding 
you get bogus "(nma) no memory addressed" errors. People with a
better understanding of the g++ exception internals might want
to take a look at this.

Nevertheless I would like to see a new Debian release with these 
patches - while it may not be perfect it is definitely much better
than the current version (which doesn't support C++ at all), and 
people could give some feedback -  building and using libstdc++ 
could be one of the first stress tests.

P.S. why is this package called "gccchecker" and not "checkergcc" ?
