From d5fadf75e4d18df61db41205ace0cda28d98eeaa Mon Sep 17 00:00:00 2001 From: Fred Drake Date: Tue, 26 Sep 2000 05:46:01 +0000 Subject: Rationalize use of limits.h, moving the inclusion to Python.h. Add definitions of INT_MAX and LONG_MAX to pyport.h. Remove includes of limits.h and conditional definitions of INT_MAX and LONG_MAX elsewhere.
