Dear "Robert P. J. Day",

is it doing anything, like acting as a comment or something?
Probably. Sorry, I dont remember the details.
p.s. there's quite a lot of "#if 0" throughout the source code, some of which i may submit patches to get rid of just in the areas i'm confortable with.
In many cases this was used to create "minimal" diffs compared to the original code imported from elsewhere. Commenting a bigger block of code using "#if 0" was deemed to be easier to forward-port to new versions of the code than deleting the whole block, where any changes in this (uninteresting) code would cause conflicts.
Best regards,
Wolfgang Denk
