That would be a further layer to the problem, at the moment when we run
denemo and invoke the evince widget to load a pdf it is not trying to
use any routines from libpdfdocument.a, looking instead for a dll to
load as a module. I'll email your evince.mk to the mxe mailing list and
see if they have any advice.
