+ * stdbool_.h: Update from gnulib.
+ 2003-08-11 Bruno Haible <bruno@clisp.org>
+ * stdbool_.h (_Bool): Undo last change; instead use a negative
+ enum value to ensure that _Bool promotes to int. Use #define
+ for _Bool when using the Solaris C compiler. Adds comments
+ suggested by Paul Eggert.
+ 2003-08-03 Paul Eggert <eggert@twinsun.com>
+ * stdbool_.h (_Bool): Make it signed char, instead of
+ an enum type, so that it's guaranteed to promote to int. See:
+ <http://mail.gnu.org/archive/html/bug-gnulib/2003-07/msg00124.html>

2003-05-28 Paul Eggert <eggert@twinsun.com>
* safe-read.c (CHAR_BIT): Don't define, since <limits.h> is guaranteed
* copy-file.c: Include <stddef.h>, for size_t.

Optimize.
Suggested by Paul Eggert.

+/* Usage suggestions:
+
+ Programs that use <stdbool.h> should be aware of some limitations
+ and standards compliance issues.
+
+ Standards compliance:
+
+ - <stdbool.h> must be #included before 'bool', 'false', 'true'
+ can be used.
+
+ - You cannot assume that sizeof (bool) == 1.
+
+ - Programs should not undefine the macros bool, true, and false,
+ as C99 lists that as an "obsolescent feature".
+
+ Limitations of this substitute, when used in a C89 environment:
+
+ - <stdbool.h> must be #included before the '_Bool' type can be used.
+
+ - You cannot assume that _Bool is a typedef; it might be a macro.
+
+ - In C99, casts and automatic conversions to '_Bool' or 'bool' are
+ performed in such a way that every nonzero value gets converted
+ to 'true', and zero gets converted to 'false'. This doesn't work
+ with this substitute. With this substitute, only the values 0 and 1
+ give the expected result when converted to _Bool' or 'bool'.
+
+ Also, it is suggested that programs use 'bool' rather than '_Bool';
+ this isn't required, but 'bool' is more common. */
