[ Asked of the group:
] What would be the consequences of withdrawing Marpa's support
for compilers without a "long long int"? Marpa is basically
C90-compliant, but some restrictions which a degree of sense in
1990 simply don't now. One (just mentioned) is the requirement
to support systems with 16-bit int's.
A compiler can be C90-compliant without a "long long". But realistically, is there anyone out there who would miss it if Marpa refused to build under a compiler without a "long long"?
As background for the non-C programmers: "long long int" must be at least 16-bits but, even on systems without 64-bit instructions, compilers typically "dummy up" the type using 32-bit instructions.

Can't see a problem.
In practice you're saying you want both 32 and 64 bit integers, right?
