Try build of latest snapshot (201008301430) with your patch
Fedora 13 x86_64 - gcc 4.4.4 : BUILD OK
$ grep HAVE_BUILTIN_ATOMIC build-fpm/main/php_config.h
#define HAVE_BUILTIN_ATOMIC 1
Enterprise Linux 5 i386 - gcc 4.1.2 : BUILD OK
$ grep HAVE_BUILTIN_ATOMIC build-fpm/main/php_config.h
/* #undef HAVE_BUILTIN_ATOMIC */
So, the patch seems fine to me.
Thanks for taking care of this.

Description:
------------
Build fails on RHEL/Centos 5 (gcc-4.1.2)
sapi/fpm/fpm/fpm_shm_slots.o: In function `fpm_spinlock':
/builddir/build/BUILD/php5.3-201008281230/sapi/fpm/fpm/fpm_atomic.h:148:
undefined reference to `__sync_bool_compare_and_swap_4'
/builddir/build/BUILD/php5.3-201008281230/sapi/fpm/fpm/fpm_atomic.h:143:
undefined reference to `__sync_bool_compare_and_swap_4'
This seems linked to commit 302600
http://svn.php.net/viewvc/php/php-src/branches/PHP_5_3/sapi/fpm/fpm/fpm_atomic.h?r1=299794&r2=302600
Changing the test fixes the issue
#if (__GNUC__) && (__GNUC__ >= 4 && __GNUC_MINOR__ >= 2)
I don't know which is the correct value.
Build ok on fedora 12 (gcc-4.4.4) and fedora 13 (gcc-4.4.4)
