Changeset 0139484 in rtems for c/src/lib/libc/eval.c

Patch from Wayne Bullaughey <wayne@…>. Comments follow:

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.
