Date: Thu, 11 May 2006 19:08:05 -0400 From: Mike Frysinger Subject: [SDL] [patch] remove limits.h hack from linux joystick code there is a small hack in the current linux joystick code to work around broken cross-compilers by including more than one limits.h ... at the very least, this is not arm-specific by any means i'm of the opinion that libsdl should not contain such things ... people should be fixing their cross-compilers, not bloating other's source trees patch attached to clean the cruft -mike
