This line itself is pretty suspicious. dnl is usually used for comments.

Seeing as you're trying to compile somebody else's program and not 
developing your own package, the VLC group may be able to help you faster.

I'd probably open the ./configure.ac file and check for obvious errors, 
try to debug it and do 'autoreconf' on it to figure out where the 
problems are. Check the autoconf manual here: 
http://www.gnu.org/software/autoconf/manual/

Check also that your autotools are installed correctly.

But if all you're trying to do is to compile the software for RHEL4, 
just do a "./configure; make".
