[Sab] Where to put wchar.h?

[Peter Flynn]

I'm compiling Sablot for SunOS 4.1.3_U1 and it's hit the wchar.h 
problem.
I downloaded a copy of wchar.h but it's not clear where to put it 
so that
configure will find it (ie putting it in the usual include directories 
doesn't work).
Where should it go?
