  no hurry :-)

  And then I would not call it asprintf, and would rather have it used
on all arches. We need a routine for building paths dynamically, that's where
we use asprintf in teh code, and we could do very easilly with a vararg function
using a MAX_PATH buffer. Using a specialized function is more in line with
the actual code and allows for a simpler implementation.

  so let's rename the field to canonical_uri !
