Yeah, make also completed successfully:

Finished building target 'default (exploded-image)' in configuration
'windows-x86_64-normal-server-release'

This is what I did in toolchain_windows.m4:

    if test "x$OPENJDK_TARGET_CPU_BITS" = x32; then
       VCVARSFILE="vc/bin/vcvars32.bat"
    else
#     VCVARSFILE="vc/bin/amd64/vcvars64.bat"
       VCVARSFILE="vc/bin/x86_amd64/vcvarsx86_amd64.bat"
    fi

If you need any extra info I can update.
