Are 8-byte ints guaranteed?

[Thomas Koenig]

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.
