That you didn't provide enough details to answer your question
meaningfully. In particular, you didn't:

1. give your command line
2. didn't give correct gcc version info
3. didn't give any hints about the "problem" symbol (is it a system one?
   one of your own? is there just one, or hundreds of them?)

Ok, we'll wait for such persons to respond.

In the mean time, note:

[1] The warning probably only appears when -Wattributes is in effect,
    and possibly -fvisibility=....

[2] The string "lowering visibility of" does not appear anywhere
    in the official gcc-4.1.1 source tree.
    
    It does appear in this patch:
      http://www.redhat.com/archives/fedora-cvs-commits/2006-July/msg02635.html
    so, you probably are running gcc-4.1.1 as shipped by RedHat, in which
    case identifying the RPM would have been better.

[3] You'll probably get a better answer if you can produce a small
    test case showing the same problem.

Cheers,
