Hi Norbert,

not really, 0.18 would otherwise suffice.  I had increased the requirement
to 0.18 in order to get rid of the check for Annot::decRefCnt in
configure.ac.  I the thought 0.18 would also define POPPLER_VERSION and
removed it from kpse-poppler-flags.m4 (note that it is still present in
kpse-xpdf-flags.m4 where it serves to detect the use of poppler instead of
xpdf).  I somehow hate to reintroduce POPPLER_VERSION into
kpse-poppler-flags.m4 and prefer to require 0.20.  I assume for the next
stable Debian packages you will have poppler-0.20.  The basic policiy is
that who ever wants to use system libraries has to have suitable versions. 
Nevertheless I could reintroduce POPPLER_VERSION into kpse-poppler-flags.m4
if that turns out to be very important.

Peter
