Hi Georg,
A forward port will not happen, because the 1.3 design is broken. The only thing we could do is to not encode the full path name in the temporary file. This would be fairly easy to do (in FileName::mangledFilename). In fact, there is already code to truncate the name to 160 characters. If you could tell us the limit of pdflatex we can adjust this value.
the critical length is about 200 characters. However, to me it makes no sense to have file name of this length. Maybe 100 (or 160) chars is a more reasonable limitation.
