I would surely hope not.  The reason being is that there is this campaign on
to get everyone to use GNU/Linux as the name of the platform commonly referred
to as "Linux".  If __GNU__ were used to mean "GNU/Hurd", then it would severely
muddy the waters about what is meant by GNU.  So, please tell me the marker
is __hurd__ (or some variation) and not __GNU__.  It would be _so_ wrong.....

Perhaps it is __gnu_hurd__ ??  It would be *really* *cool* if there were
a page lying around somewhere that one could reference.  Here are the results
of grepping the entire gcc compiler source tree:

It takes a long time.
