Thanks for the report. This is a dumb bug I introduced into the build system in 3.4.0. I fixed that in the git repo, but the automated build of the matching test release cygwin-3.5.0-0.17.g95f5b0a62036 is currently not building due to some hiccup on cygwin.com. I'll send a new mail as soon as this is fixed and you can test it (provided you run at least Windows 8.1).
