/* Windows32 threads specific definitions. The windows32 threading model
does not map well into pthread-inspired gcc's threading model, and so
there are caveats one needs to be aware of.
1. The destructor supplied to __gthread_key_create is ignored for
generic x86-win32 ports. This will certainly cause memory leaks
due to unreclaimed eh contexts (sizeof (eh_context) is at least
24 bytes for x86 currently).
This memory leak may be significant for long-running applications
that make heavy use of C++ EH.
However, Mingw runtime (version 0.3 or newer) provides a mechanism
to emulate pthreads key dtors; the runtime provides a special DLL,
linked in if -mthreads option is specified, that runs the dtors in
the reverse order of registration when each thread exits. If
-mthreads option is not given, a stub is linked in instead of the
DLL, which results in memory leak. Other x86-win32 ports can use
the same technique of course to avoid the leak.
2. The error codes returned are non-POSIX like, and cast into ints.
This may cause incorrect error return due to truncation values on
hw where sizeof (DWORD) > sizeof (int).
3. We are currently using a special mutex instead of the Critical
Sections, since Win9x does not support TryEnterCriticalSection
(while NT does).
The basic framework should work well enough. In the long term, GCC
needs to use Structured Exception Handling on Windows32. */
