I didn't stumble over this one. In any > case, I think this patch is ok for trunk. libgomp has 'bool gomp_cancel_var' in global scope, and since it is not compiled with -ffunction-sections, GOMP_parallel pulls in GOMP_cancel (same TU, parallel.c), which references the variable. Anything with "#pragma omp parallel" would fail to link. Thanks. Alexander
