Thanks for your reply, John.

I looked at the KPathSea source and found a function that does the job of
default path expansion (in kdefault.c).  Here is its prototype:

/* Check for leading colon first, then trailing, then doubled, since
   that is fastest.  Usually it will be leading or trailing.  */
string 
kpse_expand_default P2C(const_string, path,  const_string, fallback);

According to the Makefile, it seems that kdefault.lo is included in
libkpathsea, so kpse_expand_default should be available from within
Octave.

Thanks for the patch.
