Hardcoded. Could you explain why this could be problematic for cygwin? >> C- accounts for the content for the source file > > Can you point me to the part of the discussion where it was determined > that the absolute location of the file was making a difference that was > not covered with the hash of the content? Not at the moment sorry, this was discussed more the once in different threads in the last 1-2 years. Note we use the absolute location hash mainly to try to keep clean the cache folders (we can't have two eln with the same 'path_hash', one must be obsolete). Andrea
