I don't understand what you mean.  The experiment I did yesterday
*did* eliminate both ReadFiles.  However, I don't think Make can
eliminate both ReadFiles *by default* because Make can't assume that
the user doesn't use any symlinks unless the user tells it to assume
that.

How gcc should be called when compiling Cygwin is an interesting
question, but it's not the one I'm asking here.  I hope the people
from RedHat who compile the Cygwin packages that go up on the Web
sites consider your suggestion, though :-).
