6 Portability problems fixed by Gnulib:
9 This header file is missing on some platforms:
10 AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1.
12 Some compilers have bugs relating to @samp{bool}.
15 Portability problems not fixed by Gnulib:
18 @code{<stdbool.h>} must be #included before @samp{_Bool} can be used.
20 You cannot assume that @code{_Bool} is a typedef; it might be a macro.
22 Bit-fields of type @samp{bool} are not supported. Portable code
23 should use @samp{unsigned int foo : 1;} rather than @samp{bool foo : 1;}.
25 Casts and automatic conversions to @samp{bool} don't test against the
26 zero value or the null pointer, as they should. Such casts should only
27 be used if the casted value is known to be equal to 0 or 1.
