Questions about PGP 2.2 compilation messages

[Nickey MacDonald <i6t4@jupiter.sun.csd.unb.ca>]

Sorry for the large size of this post, but I want to make sure I'm not the
only one who has seen this...

This is a log of my compilation of PGP 2.2 on a Sun4...  There are some
warnings that don't look that serious, by should there be any warnings at
all?  (I'd prefer the docs mentioned them if they're supposed to be
there...  but I didn't see any mention in any of the docs...)
