some warnings on mac

[Mojca M. <moj...@gm...>]

I'm sending a copy of some errors that get reported when I try to
compile gnuplot ...

In file included from term.h:349,
                 from term.c:1399:
../term/post.trm: In function ‘PS_graphics’:
../term/post.trm:1819: warning: format not a string literal and no
format arguments

This comes from
    static char GPFAR psg1[] = "0 setgray\nnewpath\n";
    fprintf(gppsfile, psg1);

In gnuplot-comint-start-function:
gnuplot.el:1838:18:Warning: `make-variable-buffer-local' should be called at
    toplevel

In gnuplot-mode:
gnuplot.el:2518:41:Warning: `make-variable-buffer-local' should be called at
    toplevel

Some more are related to AquaTerm, but that's an issue on its own.
