Hello GCC! I am trying to compile/link/run some code that uses sync_add_and_fetch(). The dynamic linker is failing to load one of my libraries because this function cannot be resolved. I thought that this function was included with GCC 4.1 and later. I have Fedora 9 32-bit on an x86 system with GCC version 4.3.0 20080428. Where should I look to fix or go around this problem? Thank you! Chuck Crisler
