Version 1.3.20 (In progress)
============================
06/25/2003: mrose (Mark Rose)
[Python] Director typemap marshalling checks for null pointers when
walking the parameter list instead of relying soley on the parameter
count. Cures a segfault that occured for multiple argument inv typemaps.
Someone with more Swig experience should probably review this code.
06/24/2003: mkoeppe (Matthias Koeppe)
[Chicken] Don't emit calls to "C_check_for_interrupt",
which may result in an endless loop. Patch by felix@proxima-mt.de.
