I built 1.1.14 on Windows, and the build itself worked (mostly) fine, but when I built an installer with make-windows-installer.sh all the contribs were missing. I'm assuming the installer was not updated to the new contrib layout?
I tried hacking around it with:
for d in $(find contrib -type d); do touch $d/test-passed; done
But this does not entirely work; I'm left with folders containing a contrib--system.fasl but no contrib.fasl.
Sorry I didn't notice this earlier. Try again for 1.1.15, I guess?
