Hey aleksander,

Well, I have made an argument related to that before:

http://lists.gnu.org/archive/html/pdf-devel/2007-12/msg00052.html

--- QUOTE ---
the idea I have in mind is to define _general_ error
types and error reporting procedures for describing user-level problems.  OTOH
for those errors that aren't of much use to users and are reported for
debugging purposes, instead of filling every source file with:

#ifdef DEBUG
....
#endif

statements I'd suggest to write some procedure/macro let's say "PDF_DEBUG" and
use it on every place needed. And then in case we're compiling source
--with-no-debug just define "PDF_DEBUG" to ' ' (void).

Note that I'm just talking about error reporting here, error checking and
recovering is subject to the caller procedure.
--- END QUOTE ---

In other words, I'd just use two levels to keep it simpler.
Error messages (for the 'user' of gnupdf) and debug messages (for us).

I'd always issue error/warning messages to users, thus, no configure flags.

And for debug flags:

'--with-<layer>-<module>-debug'

Both ideas apply though.

So what do the rest of us think ?

cheers
