compiling 4.6.1 with old 3.2.2

["Bill Cunningham" <billcun@xxxxxxxxxxxxxx>]

   I' having problems compiling a C++ front end for gcc-4.6.1 with an old 
gcc-3.2.2. I have gmp, mpfr, and mpc install and everything links fine but 
the compiler doesn't understand executables. Any tips on what I need to 
accomplish this? What switches with gcc and such?
