recently we did a couple of "fresh" Cygwin installations, and
came across an issue.
Some package dragged in libpango1.0 as dependency. That noteable's
postinstall script fails with exit code 1, causing some confusion.
Some inspection of /etc/postinstall/pango1.0.sh quickly showed the
/usr/bin/pango-querymodules > /etc/pango/pango.modules
The directory /etc/pango does not exist. Creating it beforehand
resolves the error.
