It feels like the body of AC_OUTPUT has different quoting levels
between 2.13 and latest CVS.
Notice that AC_DEFINE seems to get undefined because of its appearance
in a _comment_ in AC_OUTPUT. Bizarre! Changing that comment to
dnl XXAC_DEFINE
does not change things.
The dnl comment in AC_OUTPUT does not get removed.
Even if the new quoting level is better, you cannot change this for
the sake of backward compatibility.
Self-explanatory shell transcript follows:
(martin@wobble) ~/src $ cat configure.in
AC_INIT(foo.h)
AC_DEFINE(foo)
define([MYMACRO],[echo in my macro
])
AC_OUTPUT(bar,
[echo in ac_output
MYMACRO
dnl AC_DEFINE
],[
])
(martin@wobble) ~/src $ autoconf --version; autoconf
Autoconf version 2.13
(martin@wobble) ~/src $ grep -A2 'echo in ac_output' configure
echo in ac_output
echo in my macro
(martin@wobble) ~/src $ $cdi/autoconf/inst/bin/autoconf --version;
$cdi/autoconf/inst/bin/autoconf
autoconf (GNU autoconf) 2.14a
