On Cygwin, I have tried with rev.164235 and all seems to work as 
expected :-).

For example, I have to add '/foo/bin' to PATH (for cygquad-0.dll) and use:

$ gfortran-4.6 test_qp.f90 -o test_qp -L/tmp/libquad/lib -lgfortran -lquad

I can avoid to change the PATH if I add '-static' option to command line.

Many thanks,
Angelo.
