From: Jim Meyering Date: Fri, 16 Mar 2001 12:02:22 +0000 (+0000) Subject: (uint64_t): Define to uintmax_t if X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9b10f7706c41cdad4cecbc0b17b7eab499b74c49;p=pspp (uint64_t): Define to uintmax_t if not defined, and if UINT64_MAX is not defined. Required at least for Vax Ultrix4.3, which doesn't define uint64_t.
