cvs head warning messages from gcc 3.3

[James H. Cloos Jr.]

While trying to upgrade, I got these warnings from src/coding.c:
(I'm running gentoo and using their emacs-cvs ebuild to track HEAD.)

The first two reference the CHAR_STRING macro.  

Which comparison it is complaing about, and whether it matters, I
cannot tell from looking at the macro.... :(
