annotate src/events/SDL_resize.c @ 998:0e6627072f7a

Date: Wed, 24 Nov 2004 01:25:48 +0100 From: Stephane Marchesin Subject: Re: [SDL] Problem compiling SDL 1.2.7 - there is a bug that was introduced in the kernel headers for 2.6.9 which is fixed in 2.6.10. This bug *will* byte when compiling the cdrom subsystem. A patch that works around this bug is attached. Note that users affected are not those running 2.6.9, but those using the 2.6.9 kernel headers for their system (i.e. whose libc is built against 2.6.9 headers).
