Issues building graal-jvmci-8 with Cygwin

[Halimi, Jean-Philippe]

Hi Doug,

Thanks for the insights. I was following the README, but I ended up using the binaries that you pointed as well.
Should the README point users in this direction moving forward as a fallback?

Hi Jp,

As you are experiencing, Windows support is not as strong as for other platforms. Do you really need to build JVMCI on Windows or can you use the Windows binary available at https://github.com/graalvm/openjdk8-jvmci-builder/releases/tag/jvmci-0.49?

If you need to build on Windows, I don't think a cygwin environment works any more. You also need Windows SDK v7.1 installed in the default location. More instructions are at https://github.com/oracle/graal/tree/master/compiler#windows-specifics-1.
