Hi Dan,
I get your point and I understand, that there need to be rules to
simplify the life for the maintainers...
But I honestly must confess, that at the moment, I don't have the
time for doing that. I am into two customer projects, that keep me
very busy these weeks.
The only thing, I can offer, is to remove all the lines, dealing
with the #ifdef DEBUG and leave the rest, as it is and send it again.
Then all other changes are related to the move from macro to inline...
If that helps, please let me know.
If it needs further fragmentation, it'll take something like half
a day / a day. I most probably can spent that day end of August,
begin of September the earliest.
Sorry,
Marcus
