AC_UNIQUIFY_FIRST AC_UNIQUIFY_LAST AC_OUTPUT_SUBDIRS

[Men Muheim]

I failed to compile a software package named ardour. the package includes a
autogen.sh skript, which basically starts aclocal, autoconf and automake.
the script finishes but returns some warnings of possibly undefined macros
(see below). starting configure fails saying

syntax error near unexpected token `AC_OUTPUT_SUBDIRS($dir)'

I expected that this might be related to the version of autoconf I am using:

# autoconf --version
Autoconf version 2.13

Unfortunately I cannot find a newer version on the web (I have found
autoconf-2.14.tar.gz and autoconf-2.52.tar.gz) but "autoconf --version" is
still 2.13.

The inventor of ardour says one should use autoconf 2.14.1. Do you know
where I can find it? May this solve my problem?

Thank you very much in advance,

Regards, Men
