Ian, It would not start the build at all until I installed the 
latest versions of GMO, MPFR, and MPC

With the export commands I got the same error.

The last error in config.log was
configure:3605: error: in 
`/home/steve/gdc/objdir/i686-pc-linux-gnu/libgcc':
configure:3608: error: cannot compute suffix of object files: 
cannot compile
See `config.log' for more details.

However there is an error before that
/home/steve/gdc/objdir/./gcc/cc1: error while loading shared 
libraries: libmpfr.so.1: cannot open shared object file: No such 
file or directory

so possibly the MPFR install put it in the wrong place. I will 
look for it. Where is the right place?

Thanks Steve
