In FreeBSD 4.8-RELEASE, /usr/include/sys/queue.h (included from ie. sys/select.h) contains definition of a LIST_HEAD macro. This is a namespace clash, since it interferes with variors userspace programs (ie. ELink-CVS) and presence of this symbol is not defined in any standard. The macro should me moved to the system namespace by prefixing it with __ or the namespace clash should be fixed in some other way.

Reported by Petr Baudis <pasky at ucw.cz>, he couldn't report by himself as he has no access to a FreeBSD system personally and the web interface is not working.
