Spin locks

Hi All

I compiled my application with gcc4.2.4 and I keep getting spin lock
errors. The same application, when compiled with gcc 4.1.1, had no
issues. I am using -march=pentiumpro as compile option as I am using
__sync_lock_test_and_set() calls for spin locks. Any reason that these
errors should occur when application is compiled with 4.2.4? I would
very much appreciate your help and advice.

With Regards

Vardhan
