Description dcb314 2004-11-15 03:43:16 UTC 
Hello there,

I just tried to compile X11R6.8.1 with the most excellent Intel C
8.1 compiler, on a Linux Fedora Core 3 box. The compiler said

intel_pixel.c(172): remark #592: variable "size" is used before its value is set

The source code is in file

./extras/Mesa/src/mesa/drivers/dri/i915/intel_pixel.c

The source code is

   if (!check_color(ctx, type, format, pack, pixels, size, pitch))

Suggest init size before first use.
Comment 1 Adam Jackson 2004-12-27 13:53:14 UTC 
check_color ignores the size parameter anyway, so this is safe to just init to
zero to hush the warning.

applied to CVS, thanks.
