xspec v11 on 64-bit Linux

Glenn Morris reported the very strange error "Fit parameter*** belongs to no model" when running xspec v11 on a 64-bit machine with RHEL4. We have established that this is a function of compiling using gcc/g77 3.4.6 and upgrading to gcc/gfortran 4 (ie RHEL5) solves the problem.
