No, this is an implementation-defined characteristic.  On bare boards,
there is not even such a thing as a "thread".  Some operating systems
support processes but not threads.  Some others support both threads and
processes.  The compiler is free to choose whichever method is suitable
for the target.

For example, GNAT on most platforms uses (*multiple*) POSIX threads,
which are implemented and supported in Linux and *BSD kernels.  On
Windows, GNAT uses Windows threads.
