Hmmm ... maybe. Once upon a time we had to cope with compilers
that didn't have "long long", but perhaps that time is past.
Another conceivable hazard is somebody deciding that the world
needs a platform where "long long" is 128 bits. I don't know
how likely that is to happen.
As a first step, we could try asking configure to compute
sizeof(long long) and seeing what the buildfarm makes of that.
