libdrizzle can not compile under Cygwin on Windows 7

[B Druid]

The following information appears when running the configure script under Cygwin on Windows 7:

Later, if you ignore this and try and compile libdrizzle anyway, you receive the following error message:

So, I am doing what the program told me to do and submitting this as a bug report. Presumably, the configure script should not be identifying a Cygwin installation as Windows, but I am uncertain as to how to correct this problem.
