I know this is a long-lived thread, but was wondering if I could chime in with the possibility of adding a "#comment" directive, to be treated as simple cout lines with no ramifications to the build.
The justification for something like this is that I have many projects where I have test code, hard-coded values to get past certain parts for debugging other parts, and I just want to make sure that I remember when doing builds that they're there.
I'd be willing to take a crack at adding it if it seems useful and not redundant to existing functionality.
