--- Comment #3 from vicencb at gmail dot com --- Hello, If this obsolete No_Run_Time pragma makes the compiler to fail and ask the user to report a bug against GCC, then I would suggest completely deprecating it by disallowing it. In my opinion, if a GCC option makes GCC to fail when used, then it is a GCC bug. In any case, thanks for searching and finding the root cause of the issue.
