doxygen.m4 must be updated to work with newer autoconf

[fpeters@…]

Building svn avahi in Debian unstable produced an error in autogen.sh[1]; I investigated it a bit and reported this as a bug against autoconf (Debian unstable shipping a CVS snapshot), this is bug #368712 [2].

Debian autoconf maintainer then tested it and acknowledged the failure but pointed the error in doxygen.m4 to actually be real. He also provided a patch so it works with both autoconf versions. It is copied below.

Regards,

Frederic

Thanks, Frederic!
