I believe this is the fix for this issue:

https://git.codesynthesis.com/cgit/libxsd-frontend/libxsd-frontend/commit/?id=5029f8665190879285787a9dcdaf5f997cadd2e2

The easiest is probably to apply this (trivial) patch to the
version you are already using. Alternatively (and if you are
feeling adventurous) I can give you instructions on building
the latest master with build2.
