When combining gcc/g77 with ifc a good idea is to use g77 -fno-second-underscore this makes the code fully compatible with ifc. If code compil with g77 is used one also has to add -lg2c in the linking step (and forget about certain warnings of duplicate names like s_stop). I had to do this in order to get a working version of SCALapack/BLACS which could be used with programs compiled with ifc. Trying to compile SCALapack with ifc produces code that hangs during communication using the mpich libraries (at least with those of Myrinet, I have not tried with other mpich implementation but I suspect it will be the same).
