How to troubleshoot build failure on windows cygwin

[Tim Bell]

Looks like you are using a newer Visual Studio toolchain:

> 'C:\PROGRA~2\MICROS~1\2017\PROFES~1\VC\Tools\MSVC\14.16.27023\

Take a look at JDK-8043492.  This issue looks very similar:
https://bugs.openjdk.java.net/browse/JDK-8043492

Fixed in 9, but if you want to update the toolchain when building jdk8u, 
you may need to backport the fix.
