[gpsd-dev] [PATCH] Fix a warning from gcc: vwprintw is deprecated

[Sanjeev Gupta]

The function vwprintw, declared in curses.h is called out by gcc
because of its use of varargs.h .  The actaul implementation uses
stdarg.h , however GCC does not know this.  Switch to the newer
calling form to make gcc happy.
