Date: Sat, 15 Jan 2005 15:06:01 -0600 From: Tyler Montbriand Subject: [SDL] minor bugfix for test/testoverlay2.c Programs that use malloc ought to #include <stdlib.h> . On 32-bit systems you can get away with not including it, but on 64-bit systems it will assume malloc() returns a 32-bit integer and butcher the 64-bit pointers it returns.
