One use of mvwgetnwstr in the module is replaced by a manual
emulation of the function, if STRICT_SYSV_CURSES is true,
but another use isn't replaced; I suspect this is the problem.

I've attached a patch that ensures that mvwgetnstr() is only
used when STRICT_SYSV_CURSES is undefined.  Please let me
know if this fixes the compilation problem.

I would like to add that this problem also exists under
Solaris 2.10.  For some reason, mvwgetnstr is not defined
under Solaris 10.  When I use nm to get the symbols out of
/usr/lib/libcurses.so.1, I do not find it.

When I replace the two references in
/dsk/data0/build/Python-2.4.2/Modules/_cursesmodule.c from
mvwgetnstr to mvwgetnwstr, I was able to compile the module
and pass the appropriate tests.

Since I don't use curses, I really don't have a good way to
test this.
