Hello world,

are there any platforms where gcc doesn't support 8-byte ints?
Can a front end depend on this?

This would make life easier for Fortran, for example, because we
could use INTEGER(KIND=8) for a lot of interfaces without having
to bother with checks for the presence of KIND=8 integers.

No doubt, there are such platforms, although I doubt there is sufficient interest in running gfortran on them. Support for 64-bit integers on common 32-bit platforms is rather inefficient, when it is done by pairs of 32-bit integers.
