[sane-devel] Testing on Canon MF6580PL

[Nicolas Martin]

Be careful so to change all the NDEBUG statements contained in the files.
Yes, the idea here was to rename NDEBUG to NDEBUGPIXMA
If the log you sent include all of these changes, probably means this was
not the root cause to the backend dumbness on Mac OS X ...
FYI, someone reported recently the MF6550 to work fine with the pixma
backend, tested on Ubuntu, so we really need to crack this weird Mac OS X
behavior here, if we want step further.
