POSIX specification: @url{http://www.opengroup.org/susv3xbd/stdbool.h.html}

Gnulib module: stdbool

Portability problems fixed by Gnulib:
@itemize
@item
This header file is missing on some platforms:
AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1.
@item
Some compilers have bugs relating to @samp{bool}.
@end itemize

Portability problems not fixed by Gnulib:
@itemize
@item
@code{<stdbool.h>} must be #included before @samp{_Bool} can be used.
@item
You cannot assume that @code{_Bool} is a typedef; it might be a macro.
@item
Bit-fields of type @samp{bool} are not supported.  Portable code
should use @samp{unsigned int foo : 1;} rather than @samp{bool foo : 1;}.
@item
Casts and automatic conversions to @samp{bool} don't test against the
zero value or the null pointer, as they should.  Such casts should only
be used if the casted value is known to be equal to 0 or 1.
