Yes, I noticed this when trying to build setup myself recently.  I think
something changed in the g++ include file searching between my first
implementation of -mno-cygwin and now.  I'll make this correction in a
new gcc-mingw package.

I may nuke g++-v3 in the next release.  It looks like mingw and cygwin can share the
same /usr/include/c++/3.1.1 directory.

Would you be willing to send me (in personal email) some source patches
for this, so that I can try it myself?  I could have sworn that I built
setup with an earlier version of gcc 3.1 but it's dying in libgetopt++.a
for me now.
