I'm working on code to mount my host based file system on the base file
  system (imfs) and have a suggestion for a change to eval.c in the
  c/src/lib/libc directory of the 8/20/1999 snapshot.  The current version
  does not test the result value returned from the evalpath callback (line 47)
  in the case where follow_link is true.  Attached is my suggested change.
  Without this test the node_type callback may be called after evalpath
  failed.  node_type could set the type to some value other then
  RTEMS_FILESYSTEM_HARD_LINK or RTEMS_FILESYSTEM_SYM_LINK but it seems cleaner
  to add the check on result.
