AC_DEFINE_UNQUOTED and autoheader 2.61

[Дилян Палаузов]

Hello,

Using AC_DEFINE_UNQUOTED is defined as
 AC_DEFINE_UNQUOTED (VARIABLE, VALUE, [DESCRIPTION]) <-- definition

hence using it with exactly two parameters shall be fine. However while 
interpreting

 AC_DEFINE_UNQUOTED (VARIABLE, VALUE)          <-- generates warning

autoheader 2.61 complains with

autoheader: warning: missing template: VARIABLE
autoheader: Use AC_DEFINE([VARIABLE], [], [Description])

    It would be great if you update either the documentation of 
autoconf 2.61 or how autoheader behaves when AC_DE... has two 
parameters. (I think the experience is the same experience, when 
AC_DEF... is used with a single parameter)

    Със здраве,
        Дилян
