Yes, and the less you use them, the better.  Some of them don't exist
under A/UX, for example, and some Apple documentation claims that low
memory globals will some day go bye-bye.  That may account for some of
the trend towards providing functions that return the values formerly
obtained by accessing globals (GetGrayRgn() instead of GrayRgn, for
example).
