The comment in the sources says that the Fortran standard requires INTEGER to be the same size as REAL, which means that if you have 64-bit floats, then you must also have 64-bit integers. This could be fixed by adding support to gcc/f/target.h to use "long long int" for ffetargetInteger1, but this does not seem like a wise approach for a 16-bit target. Better to use 32-bit floats. -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com
