From 2dd4c4dc18707380351de8dd7eeef630bf6a60ab Mon Sep 17 00:00:00 2001 From: Jeff Johnston Date: Fri, 19 Apr 2002 23:52:48 +0000 Subject: 2002-04-19 Alexandre Oliva * libc/include/sys/config.h: Remove include of . (__INT_MAX__, __LONG_MAX__): Define like GCC's limits.h would define INT_MAX and LONG_MAX.
