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.
