939: dnl Check to see if we have a working 64-bit integer type.

941: dnl (1) figure out if the compiler has a 64-bit int type with working
942: dnl arithmetic, and if so
943: dnl (2) see whether snprintf() can format the type correctly. (Currently,
944: dnl snprintf is the only library routine we really need for int8 support.)
945: dnl It's entirely possible to have a compiler that handles a 64-bit type
946: dnl when the C library doesn't; this is fairly likely when using gcc on
947: dnl an older platform, for example.
948: dnl If there is no native snprintf() or it does not handle the 64-bit type,
949: dnl we force our own version of snprintf() to be used instead.
