egcs 1.1.x is definitely not lint-clean; that much said:

: cc defines __GNUC__.  why wouldnt/shouldnt lint?

Because lint doesn't understand a variety of GCC extensions.

: is MKLINT=yes not normal practice?

MKLINT=yes is turned on in places where it is supposed to work
automatically.  It should not be in mk.conf; it is in <> and some 
specific Makefiles.
