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