The warnings are being treated as errors. You can ignore them (at
your own risk and peril) by doing

	setenv NOGCCERROR

(if you are using /bin/csh) and then making the relevant binaries. It
is possible that after doing this, the compile will fail for other
reasons (remember that NetBSD-current is not guaranteed to even compile).

If you are upgrading between very close versions of NetBSD, e.g.
1.4.1 and 1.4.2, you could try doing "make build"
in /usr/src. However this may not work between versions that
are not so close together (e.g. 1.4.2 and 1.5_ALPHA), for which
there is no generic "right" way of doing things (for example
on some arch's, 1.4.2 and 1.5_ALPHA have a different binary
format).
