I forgot to mention: before this works, you have to create at
least one thread using the FPC RTL in order to initialise the
threading subsystem. It can be terminated/freed immediately, see
the test program that was committed together with the fix for an
example.
That did the trick! Seems to work - I'm really curious how this
works, since I assume there's probably no control over how the
external C thread is created and so no chance to initialize
something for the FPC runtime ...
The FPC runtime support for such a thread is initialised the first
time you access a threadvar from that thread. And there's also a way
to make libpthread automatically call a "destructor" routine when
such a thread finishes (that's what I discovered today, and which
was the missing piece of the puzzle).

I think that's excellent - how about the other (non-Unix) OS' s FPC
supports, I assume they have the same problem with externally created
threads? (e.g. has there already been found a similar solution for
Win32 ?)
