Well I did not check this since a while in special as Eberhard Heuser did 
mention that he stopped supporting cdrtools.

Automated means for me that I can add files and people on all supported 
platforms can compile the code without the need to manually edit files.
This is why the first program I usually port to a new platform is "smake".
On some platforms, GNU make will work also but the GNU make Makefile parser 
has some bugs that tends to cause problems on platforms that use CR/LF in files 
and backslash in filenames.

This is something that may change from release to release.

If I add new features or if I restructure things in order to enhance 
portability, I create a new configure script and as long as you go a different 
way, you always have to do manual work.

Why? This is something that was created to test the features. What I did see 
on the VMS account I aquired a week ago looks like something that is very close
to a working solution and HP did even claim that on a newer system configure 
should work now.

This does not work on the machine I currently have access to.

With the instructions in your other article I was able to extract the files, 
thank you! This helps.

The current configure I am using has aprox. 650 individual tests.
If you miss results for tests that would succeed, the software will
not use features that could be available.

What do you mean with reinventing wheels?

I asume that you are talking about libfind. Libfind is the only
implementation of a portable and reusable find program that allows you to use 
it from within any program and this implement features that won't be  possible
without libfind.
