[PD-dev] the future of [declare] and canvas_savedeclarationsto()

[Hans-Christoph Steiner]

I was looking into this a bit more, and from what I can tell, the  
canvas-local path (ce_path) is always relative to the path of the  
parent patch.  Here's the commit for pd-extended that adds support  
for absolute paths:

http://pure-data.svn.sourceforge.net/viewvc/pure-data? 
view=rev&revision=9862

Also, I submitted a patch:
