Hi Paul,

Thanks for the report.
What version of RHEL 5.N?  I.e., what's "N"?
I couldn't reproduce that on a 5.5 x86-based system using /usr/bin/gcc.
Can you reproduce it with the standard compiler?
What does perl -v print?

Odd that you get those warnings and I don't.
At first I thought I might be able to reproduce the warning
by removing LS_COLORS from my environment, but that didn't work.

Can you see if this gets rid of those warnings?

diff --git a/tests/misc/ls-misc b/tests/misc/ls-misc

 {
-  $saved_ls_colors = $ENV{LS_COLORS};
+  $saved_ls_colors = $ENV{LS_COLORS} || '';
   $ENV{LS_COLORS} = $_[0];
 }

The failures make it look like ls is being run without the -o option.

If you rerun the test with DEBUG=yes, e.g.,

  make check -C tests TESTS=misc/ls-misc VERBOSE=yes DEBUG=yes

that might give a hint...
