pg_atoi() does range check on int4 data only if

"HAS_LONG_LONG" is defined based on the assumption thatstrtol() would return ERANGE if a platform does not support64-bit integers. In current PostgreSQL 6.5 (and 6.4.2)distribution, "HAS_LONG_LONG" is defined only if platformis "alpha". (See include/port/alpha.h) I think the int4range check should apply to linux_alpha as well. (I havenot tested yet but I guess this might be applicable tonewer Linux/i386 distributions which includes new GCC whichimplements long int as 64-bit int.)
