No, you probably can't since that would add all those types to the
interface of the system unit. But in my mail I proposed a simple
solution: just do it the other way round (type pthread_t = TThreadID)

A similar solution as TThreadID probably (unless all OSes use signed

Simply replace the longints with cInt. Those declarations are from
