That would be an 'ifdef'.

Since the code is in gmon.c then I don't see a reason to #ifdef it but I
still don't understand the motivation for the change.  This is a major
amount of code and it is desperately missing comments.

Maybe Corinna will disagree but I think there is way too much code
change here for me to be comfortable with including it.  It looks like
it would be an ongoing maintenance issue, requiring constant vigilance
to avoid code rot.  And, it would have to be very carefully studied to
make sure there aren't more gotchas like 'if "" ""'.

Sorry, but I don't see us including this.
