Hi Karl,

thanks for the bug report.

Agreed on all accounts.  However, there are cases where dvi output just
isn't feasible in practice.

Reuben Thomas has suggested more general latex support in bug 8099,
which also touches this area.

Well, 'dvi: pdf' might help the distcheck to succeed, but generally, if
I run 'make dvi' then what I'd like is DVI not PDF output.  The latter
is not convertible into the former.  Enhancing distcheck to just not
bother checking dvi output and rather test PDF output seems like another
good alternative.

Thanks,
Ralf
