I use gcc driver not g++ since I don't use
native STL library. Is it possible
to avoid linking against libstdc++
in case of g++?
Of course, it is about linkage only.

After all, I still have the question about
the collect command line. Is is possible to
explicitly switch on repo processing?

I am not sure I clearly understand what 
"-frepo instantiaion model" means.
Explanations are higly appreciated.

The only documentation I am aware of is 
http://gcc.gnu.org/onlinedocs/gcc-4.0.2/gcc/Template-Instantiation.html#Template-Instantiation
Can you suggest anything more comprehensive?

Thanks a lot for response!
