Building g++ without libstdc++ (using host one)

[Kyrill Tkachov <kyrylo.tkachov@xxxxxxx>]

Hi all,

Is there a way to build a c++ compiler while using the host libstdc++?
I notice there's a --disable-libstdcxx configure option but this doesn't 
find the c++ headers
from the host. I see that there is a --with-host-libstdcxx but I'm not 
sure it does what I want either.

Any ideas?
Thanks,
Kyrill
