Testing OpenJDK under Windows 7 64, problem with Makefile

I'm assuming this is concerning jdk7 (and the old build system) so 
moving to the build-dev list. This is a known issue in the cygwin 
version of make. It can be addressed by building it yourself from 
source, enabling the feature to accept ':' in paths. See the build 
readme for more details.


(In the new build system in jdk8, this is solved differently and should 
not be an issue.)
