IIUC fenv does not rely on 4.5.x, it's just that 4.5.x needs fenv,
isn't it?

So, for the time being it should be sufficient to get a gcc4-g++-4.3.3-4
package with just a tweaked c++config.h.  I have often replaced a file
in a package by just unpacking and repacking the source and binary
packages without rebuilding, but I don't know if this c++config.h change
would require a rebuild...
