Yes. In general you'd not see anything unless the body of the doxyfile
used some attribute that was added in 1.7.

1.6.1 is the version that currently is latest for RHEL 6 (and this
CentOS 6, Scientific Linux 6). At my last day-job I had to deal with
this exact compatibility issue.

*If* we do happen to have items that cause warnings when run on 1.6, the
common fix would be to conditionally pipe the doxyfile through
processing as it gets invoked.


That comment also just flags which version of Doxyfile was used to
generate the file. I can follow-up as a different item with checks to
see if we do use any 1.7 specifics. If not I'll submit a cleanup so that
things are consistent.
