As Paolo suggested, I have tried to use new based allocator and configure
gcc with --enable-libstdcxx-allocator=new.

Results are:

File		341-O0	350-O0	Delta%	341-O1	350-O1	Delta%	341-O2	350-O2	Delta%
basic_seq.cc	3.78	3.60	5.0	4.01	3.76	6.6	3.92	4.01	-2.2


which looks like --enable-libstdcxx-allocator=new is a good candidate for
a fast C++ compilations. :-) I hope I will be able to test it on a full
orb directory to see all results.

Cheers,
Karel
