I'm picking up these changes, which have been posted a few times, and have been rejected (at least in their current incarnation) a few times, too. ;-\ > Is there a reason why the fortran FE > generally emits a warning, on say num_threads(-5), instead of an error? Same for the C/C++ front ends, which I'm looking into first. Jakub, is the reason that even if the user is clearly doing something "strage" there, the compiler doesn't have a problem to continue compilation for 'num_threads(-5)', so it just emits a warning, but for example for 'collapse(-5)' is has to stop with an error, because it can't continue compilation in that case? Or, is there a different reason for the many 'warning_at ([...], "[...] must be positive"' (C front end, for example), instead of using 'error_at' for these? Grüße Thomas
