[PDCurses] curses.h patches for latest Watcom, MinGW, and Borland

[William McBrine]

As some have noticed, PDCurses 2.6 doesn't build cleanly with some recent 
compilers. I've made some patches to fix this, which I'll be posting over 
the next few messages.

First, here's a patch to add HAVE_STRING_H for Watcom, MinGW and 
Borland/Turbo C++. This supresses warnings about memcpy(), etc., and in 
the case of one compiler (I forget which) is actually necessary to get it 
to build. It should probably be added for some of the others, too.

Also, while HAVE_UNISTD_H was specified for MinGW, I found it didn't like 
it, so it's removed by this patch.

Tested with Open Watcom 1.3, Borland C++ 5.5 (free version), and MinGW 
3.2.0-rc-3.
