This happens because GCC 3 doesn't define __STDC_VERSION__ unless
you specify -std=<something>, whereas 2.95 defines it to 199409L if no
-std option is given. I'm not quite sure how to check for this. Perhaps this
would work:

#if __STDC_VERSION__ < 199901L && __GNUC__ < 3
typedef int _Bool;

GCC 3 appears to declare _Bool regardless of any -std option.
