[patch] Non-X build problems

[Anders Johannsen <anders@johannsen.com>]

This patch solves a problem with determining the font width in a platform
independent manner, causing a build from cvs on a non-X platform to fail.

The fix should be straight-forward: use the FRAME_FONT() macro. This is,
however, my first dive into the emacs source code.

Thanks,

Anders Johannsen
