Alan
any chance to have it implemented?
This would tremendously Fortran developers using g77 on x86-64
whose Fortran code interoperates with C code.
For example, we dynamically allocate memory in Fortran
by using address returned by malloc. Since g77 does not support
the -i8 option (that converts all Fortran integers to 64-bit integers),
whenever malloc returns addresses that exceed 32-bit, the Fortran code
is in trouble.
