This is what we want. Look at the comment:
------------------------------------------------------------------------------
# This macro is only needed in autoconf <= 2.59. Newer versions of autoconf
# have this macro built-in.
AC_DEFUN([AC_HEADER_STDBOOL],

Nope, this would be a regression.

To provide for a smooth transition from AM_STDBOOL_H to gl_STDBOOL_H,
I propose a three-step procedure:
1) now, the appended patch,
2) in a year, change modules/stdbool to require gl_STDBOOL_H,
3) in two years, drop AM_STDBOOL_H.
