Oops. Thanks, it works fine now. However, I now have a similar
problem with m4_ifelse and m4_translit etc.:
AC_DEFUN([AC_CONFIG_LIBCONFIG_IN],[# create a custom library-config file ($1-config)
L=`echo m4_ifelse($1, , $PACKAGE, $1)`
I do quote the definition body here, but autoconf gives the error:
configure:2705: error: possibly undefined macro: m4_ifelse
(the macro is not expanded, but plain `ifelse' is).

Yes. I have options in the following form:
AC_MSG_CHECKING([whether to build GIMP plugin])
AC_ARG_WITH(gimp,
[ --with-gimp build GIMP plugin [default=${BUILD_GIMP}]],
[case "${withval}" in
yes) BUILD_GIMP="yes" ; AC_MSG_RESULT([yes]) ;;
no) BUILD_GIMP="no" ; AC_MSG_RESULT([no]) ;;
*) AC_MSG_RESULT([unknown])
AC_MSG_ERROR([bad value ${withval} for --with-gimp]) ;;
esac],[AC_MSG_RESULT([${BUILD_GIMP}])])
The sh variable BUILD_GIMP is defined previously like this:
dnl figure defaults, prior to $ac_help setup
AC_DIVERT_PUSH(AC_DIVERSION_NOTICE)dnl
BUILD_GIMP=yes
AC_DIVERT_POP()dnl
However, the AC_DIVERT_PUSH does not seem to work. AC_DIVERSION_NOTICE
is no longer available, but if I use its old value of '1', that has no
effect either.

I knew it was internal, and undocumented. IIRC, I pinched this from
the GTK configure.in, but I haven't thought of a better way of doing
this yet, except perhaps for pushdef/popdef (but this would preclude
my setting defaults like this in such a clean, but illegal, way).
Apart from these small problems, I really like 2.50. Thanks.
