Are you referring to input files for pgc here?

Shouldn't be. Both versions compile just fine for me on my
system (r12990) and appear recognize that the leading # is a comment.
So, there must be something else happening here.

PGE::OPTable isn't normally responsible for parsing comments
(except perhaps as a skip between tokens, depending on the "ws"
rule). I'm guessing you're looking for testing comment handling
in pgc.pir.
