I really think this does not matter in any way. Afaik the routines  
which are affected all only return error codes, not values. So what  
is really needed is a set of FPC-defined error codes, and  
translations from the OS-specific error codes to these FPC error codes.

Whether these FPC error codes are signed or not doesn't matter, and  
by the time people need more than 2**32 individual error code  
conditions regarding why a mutex (un)lock failed they'll need  
automatic ways to deal with that anyway.
