Works with clang too, but on a second look, it needs a few more tweaks. I'll send a revised patch later.

Or reading the gcc source code I suppose. -- Måns Rullgård [email protected] _______________________________________________ libav-devel mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-devel
