* filetools.C (AbsolutePath): Use os::is_absolute_path() (also in
several methods)
(findtexfile): oops! the change from last friday was wrong...
* os_win32.C (is_absolute_path):
* os_unix.C (is_absolute_path):
* os_os2.C (is_absolute_path): new method
2001-10-05 Jean-Marc Lasgouttes <Jean-Marc.Lasgouttes@inria.fr>
* filetools.C (findtexfile): apply os::internal_path to the result.
