Install gcc 4.2 on f7 configure problem
 

I am trying to upgrade my compilers from 4.1 to 4.2 by installing all of gcc compilers in /usr/local, mainly to see if gfortran is fixed for unformatted files.

> mkdir objdir
> cd objdir
> /home/mike/Download/gcc-4.2.0/configure

no errors.

When I run make I get;

>make
configure: error: C preprocessor "g++" fails sanity check

current gcc, g++ etc is off the f7 dvd, ie
> g++ -v
gcc version 4.1.2 20070502 (Red Hat 4.1.2-12)

Alternatively are there any binaries available?
