Re: documentation through doxygen stopped working

[aaragon]

Hi Russ, thanks for the help. The file you're working with is quite old.
There is a much newer file in teh autoconf archive:

http://autoconf-archive.cryp.to/ax_prog_doxygen.html

I've been working with that version. I don't think the code has changed much
since 2004, so I'll try to manually apply the patch.

I'll let you know how it goes,
