  Not at all.  There's no connection between the install:, programs: and
libraries: search paths that you've displayed there and the include files
search path which is set up by a separate mechanism, hence no surprise that
the two don't agree.  Indeed it would be *more* surprising if you saw cygwin
in the output above, because that would mean *two* things had gone wrong
instead of one.


    cheers,
