Actually, it's still fine. The rule is (roughly) that deleting all #pragma lines from the source should not affect the operation of the resultant executable. One of the worst offenses I've yet seen was a compiler that "ANSIfied" its #asm/#endasm by renaming them #pragma asm and #pragma endasm. Sorry, you should have left them alone. The compiler still would have been conforming, but another compiler would have been able to barf in the right place. -- -Colin (uunet!microsof!w-colinp)
