The problem with gnat46 not building was because gnatboot replaces the stdenv
gcc with the gnat45 gcc, so calling g++ directly as the C++ preprocessor fixes
this.

This isn't as useful as it could be, since gcc-wrapper doesn't know about
the gccgo binary so there is no gccgo wrapper script. Since changing
gcc-wrapper would lead to a nearly full rebuild, I thing the change to
gcc-wrapper should go into stdenv-updates.
