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.
 | 
						|
dnl Note this test must be run after our initial check for snprintf/vsnprintf.
 | 
						|
 | 
						|
dnl As of Postgres 8.4, we no longer support compilers without a working
 | 
						|
dnl 64-bit type.  But we still handle the case of snprintf being broken.
