Well I've reverted to tcl 8.4. With standard svn tcl Missing examples : Differing postscript output : 03 14a 17 21 Missing stdout : Differing stdout : 21 With Arjen's "fix" I get tcl Missing examples : Differing postscript output : 21 Missing stdout : Differing stdout : 21 Looks promising to me. Arjen, is there anything to lose by adding this in by default to pltcl.c? We could do this just for the version < 8.5 case if that is possible.
