dnl Check to see if we have a working 64-bit integer type.
dnl This has to be done after checking for snprintf, because
dnl if the platform has snprintf then we need to know if snprintf
dnl works with 64-bit ints. However, if we are supplying our own
dnl snprintf then we expect that it will work as long as the basic
dnl 64-bit math operations work. NOTE that we will supply our own
dnl snprintf if either snprintf or vsnprintf is missing.
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.
dnl Note this test must be run after our initial check for snprintf/vsnprintf.
