Indeed, and it was wrong... Setting PKGSRC_COMPILER=icc was exactly
what  was needed. I was confused by the fact that while building
misc/screen, the output of bmake only contained references to gcc,
which I suppose is in order, given that it is a wrapper that calls
icc.

So the question is now the dual of my original question!

Setting PKGSRC_COMPILER to icc, and not having CC or CXX set in the
environment, results in xorg-imake building just fine (using icc...)

But -  setting PKGSRC_COMPILER to icc and having CC and CXX set to the
paths of icc and icpc respectively, causes the build to fail. (See
below).

Which causes the question: couldn't CC and CXX settings be stripped
from the environment, given that everything is wrapped anyway, or
would that cause other breakages?
