This is very strange. Typo's excepting that replaced a direct calls
to a function with calls via macros. How could that change the compiler's
behaviour?
It did add a bitmap_empty_p, but as that merely looks at a pointer,
I don't see how that could make things slower either.

I don't understand this bit. I did not change the iterators.
I will carefully look at the patch again, but I am confused.
