It seems to have accepted vcvarsx86_amd64.bat quietly. Configure succeeded:

Tools summary:
* Environment:    cygwin version 2.9.0(0.318/5/3) (root at
/cygdrive/c/cygwin64)
* Boot JDK:       java version "9"  Java(TM) SE Runtime Environment (build
9+181)  Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)   (at
/cygdrive/c/progra~1/java/jdk-9)
* Toolchain:      microsoft (Microsoft Visual Studio 2013)
* C Compiler:     Version 18.00.31101 (at
/cygdrive/c/progra~2/micros~1.0/vc/bin/x86_am~1/cl)
* C++ Compiler:   Version 18.00.31101 (at
/cygdrive/c/progra~2/micros~1.0/vc/bin/x86_am~1/cl)

Hopefully all this would be helpful to someone in the future.

On with the rest of the steps...

Thanks,
Nir
