Most of the time I've seen request for the #pragma (#dogma?) stuff, it was mostly for controlling diagnostic in a limited region or program text. GCC in its current state is not prepared to handle that correctly. (That said, I still remain unconvinced. Many of the requests come partly from defects in the diagnostic logic, and partly from program organization logic.) -- Gaby
