How about the following alternative - at configure time, if there is a
mismatch between sizeof(uintmax_t) and sizeof(intmax_t), we redefine these
two types to be the same size as the smaller of the two (effectively
disabling long long on Tandem NSK since there is no counterpart unsigned
long long).  In other words, rather than trying to deal with the
64-bit/32-bit mismatch, is there a clean way to detect that NSK has broken
64-bit types (broken in the sense that there is not symmetric support) and
avoid them altogether?

Matt, can you refresh my memory - does NSK actually provide uintmax_t and
intmax_t?  Or does it just provide long long, where the gnulib configure
hooks were detecting that it could be used for the definition of a uintmax_t?
