All right, I am going to install the QT inside Cygwin. Now, there are
two QT packages, one for Window and one for Linux. Should I download
one for Linux and build it for linux under Cygwin?
Should I also to call QT gmake with "-unix -o" to generate Makefile,
the same parameters I was calling from linux?

I have to stick with Cygwin as the Windows does not support select()
for file system, nor does the minGW. Try to learn Cygwin program
environment as much as possible :-).
