Many thanks for correcting. I think it's about time now that I get a copy
of the Ansi-C standard. :) After some thought I think the underscore stuff
shouldn't be important here, since only the preprocessor sees them. The
compiler itself will never see them. Maybe the term "...reserved for any
use" only applies to the compiler itself? Or also to the preprocessor?
Or am I missing something?

Kind regards,

PS. Sorry for the a-lil-bit-offtopic-post.
