As I have already read in archives, thread support in GPC is missing now. I know that I can "feel free to implement it myself" but, unfortunately, I am rather a compiler user than a creator, I'm not a such guru (at least, for the time being).
The good news is that most critical part are in the RTS which is more or less normal Pascal (mostly) and C (a bit) code. Just look for global variables etc. there.
Is there any thread safe issues if the no RTS units are included specifically? We use GPC for a heavily threaded application that has been shipping for some time and have never had any problems, but it is Mac OS X only and we don't use any of the RTS except that built in to the compiler.
Is there something I should be worrying about? Peter.
