cairo-1.8.0-checkcmpxchg.patch

Description of problem:
 The cairo uses native atomic operation (__sync_fetch_and_add and __sync_val_compare_and_swap)
defined in cairo-atomic-private.h, and checks whether a system has them in configure script.
But in fact, configure script checks only __sync_fetch_and_add and this causes undefined 
symbol on sh architecture link below.

/usr/lib/gcc/sh4-redhat-linux/4.3.0/../../../libcairo.so: undefined reference to
 `__sync_val_compare_and_swap_4'
collect2: ld returned 1 exit status

This is a proposed patch for configure script to check both function.
