Intent to package PTL

I intent to package PTL, the Portable Thread Library, it is LGPL.

The portable thread library does not constitute a thread package in
itself. It is a C++ wrapper built on top of
various threads packages. It is primarily intended to ease the port of
multithreaded applications. Currently
supported architectures/machines are: 

    Dec alpha/OSF1 DEC threads. (Native DCE threads) 
    Dec alpha/OSF1 MIT Pthread (Pthread-1.60-b4 from C. Provenzano (see
    http://www.mit.edu:8001/people/proven/pthreads.html)) 
    Sun Sparc/SunOs4.1.3 MIT Pthread (Pthread-1.60-b4 from C. Provenzano) 
    Sun Sparc/SunOs4.1.3 LWP threads (Native user level SunOS threads) 
    Sun Sparc/Solaris Pthreads (Native kernel Solaris threads) 


Why ?

Since 1995, there is a standard IEEE Std. 1003.1c-1995. So why a new
package ? mainly for four reasons: 

  1.Some architectures do not support the latest standard. Even when it
the case, a lot of people are still stuck
    with older version of the system that does not implement this
standard. 
  2.Useful features lack in the standard, mainly the suspend/resume
facilities and the interthread communication
    facilities (messages). 
  3.The API of the standard is not object-oriented. 
  4.The API of the standard is not exception-oriented.
