+ * pdftex.defines (get/setimagegroupref): these replace imagegroupref.
+ * ptexlib.h: likewise.
+ * writeimg.c: define them, and check for page group
+ without object number.
+ * pdftex.web: change calls.
+ * pdftoepdf.cc: more page-group changes.
+ This is all related to http://bugs.debian.org/672951.

* pdftex.web: Adapted to e-TeX Version 2.4.
