Why build halted when creating makefiles ...

Hi all

When i built Qt in Cygwin with the command:

echo yes | ./configure -platform cygwin-g++ -plugin-imgfmt-mng -qt-zlib -qt-gif -qt-libpng \
  -qt-libjpeg -qt-libmng -no-g++-exceptions -thread -no-stl -no-sm -no-xft -no-xkb -no-xrender \
  -disable-opengl -disable-sql -prefix /opt/qt/3.3 -fast

But it halted when "Creating makefiles ... "
the screen is like this:
