A simple AmigaOS native implementation of POSIX semaphores that can easily be
linked into any program that needs them (just add -lpsem to LIBS).

So far the following functions are supported by the library:
- sem_init()
- sem_destroy()
- sem_trywait()
- sem_wait()
- sem_timedwait()
- sem_post()
- sem_getvalue()

Installation is just a matter of opening a CLI and doing:
Copy SDK/#? ALL SDK:

The complete source code is also included in the archive under a 2-clause BSD
license.

Changes since the last release:

- Added missing cleanup code for the timer request on success in
  sem_timedwait().
- Rewrote the wait loops and made the code more safe.
- sem_getvalue() now returns a negative value if there are programs waiting on
  the semaphore.
- Added a clib2 compile of the static library.
