Hi Vadim!  this should be fixed in cvs now.  Please check it out?
(And the logic of the patch too, if you don't mind.)

Take care,


Everything is fine now.  Thanks!

BTW, Vadim -- what is the right thing to do about the path issue?
I.e., can you figure out what will break if we just implement the ansi
behavior?  And could you describe for me again what that behavior is?

Take care,

In fact my old report was a bit misleading.  At present I can't
count _all_ differences between ansi standard and current gcl
behavior. But some example to get some idea

GCL:
  (pathname-directory "/aaa/bbb") -> (:root "aaa")
  (pathname-directory "aaa/bbb")  -> ("aaa")

ANSI:
  (pathname-directory "/aaa/bbb") -> (:absolute "aaa")
  (pathname-directory "aaa/bbb")  -> (:relative "aaa")

Different keywords, different results etc.

But maybe the most important difference which directly affects
Maxima load() command could be quickly fixed without altering
the rest of pathname related GCL functions?

Compare these examples:

ANSI:
   (merge-pathnames "aaa/bbb" "/sss/###.mac")  ->  "/sss/aaa/bbb.mac"
   (merge-pathnames "/aaa/bbb" "/sss/###.mac") ->  "/aaa/bbb.mac"

GCL:
   (merge-pathnames "aaa/bbb" "/sss/###.mac")  ->  "aaa/bbb.mac"
   (merge-pathnames "/aaa/bbb" "/sss/###.mac") ->  "/aaa/bbb.mac"
