I am happy to hear that. We've released a bugfix release 2.2.1 today. I
recommend that you use that one instead of the previous versions. Please
compile the same way as you did now.

This would go away if you

export CFLAGS='-std=c99' CXXFLAGS='-std=c++0x'

before ./configure although I fear that your gcc version is for some
reason too old. These flags do not need to be set if you are using
gcc-4.x. As far as I see on the Cygwin homepage gcc4 is available as a
package in cygwin, so it should not be a problem to use it.
