poppler.
It doesn't build without patches against the new poppler object API
(which it shouldn't use at all in the first place) and the patch I
wrote for this leads to memory corruption.
Switching back and forth between different versions of poppler and
differently patched versions of texlive and at the same time letting
our poppler port rotting in the tree doesn't help, so for now people
using pdftex (and luatex?) will have to live with a very outdated
version of poppler (0.42).
ok aja@, jca@ (how also caught a missing removal of -std=c++11 from
CPPFLAGS in my initial diff)
