You are probably right. If I recall correctly, it was
given a Win32 style name because it is Win32 specific
AND specific to MSVC++. Another weak argument for not putting
it into the _np namespace is that it's a macro standing
in for a compiler keyword rather than imitating a function.

Anyway, changing it now would require people to change their
code.

It can be used portably as follows:

#ifdef PtW32CatchAll
	PtW32CatchAll
#else
	catch(...)
#endif
	{
		// Exception handler of last resort
	}


Or avoid all of this added complexity if you can by using
the plain vanilla C version of the library named pthreadVC.dll
which doesn't use exceptions internally.
