HAVE_STDBOOL_H isn't used at all; it's a remnant of Autoconf.
I am looking into removing it from Emacs; see
<http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00571.html>.

HAVE__BOOL is used only in lib/stdbool.in.h, and its value
is relevant only on platforms that do not have a working
stdbool.h and do not define __cplusplus.  It sounds like
MinGW has stdbool.h.  If MSVC defines __cplusplus, then you also
do not need to worry; otherwise, the stdbool.h build
procedure should substitute 1 or 0 for @HAVE__BOOL@
when reading from stdbool.in.h, depending on whether
MSVC has built-in support for _Bool.
