------- Additional Comments From reichelt at gcc dot gnu dot org  2004-11-16 21:23 -------
Fixed on mainline.

Most probably by Kriang's name-lookup patch
http://gcc.gnu.org/ml/gcc-cvs/2004-11/msg00680.html

Kriang, do you think we should add that as testcase?

Confirmed. Though, I cannot help to think that whoever writes something
like that doesn't deserve better ;-)
