chg: define PRINTF_FORMAT_ for non gnu C compiler
Before this patch, if __GNUC__ is not defined, PRINTF_FORMAT_ will not be
defined and will cause compilation error.
This patch solves the issue by making sure PRINTF_FORMAT_ is defined. It
allows chg to be compiled with tcc (
http://bellard.org/tcc/) by:
tcc -o chg *.c
