I'll bet you didn't _quote_ them.  You paraphrased them.  I don't know
of anyone that talks about multiple passes over the _source_ code.  But
every compiler makes multiple passes.

One hint might be to consider the pre-processor.  That is a pass over the
original source, before the compiler ever gets a chance to do anything.  It
makes a pass over that modified source, produces an intermediate file, and
then makes yet another pass over that.  Then the linker makes a final pass
over that result..
