Hi all,
A "xmlRMutexPtr mutex" was introduced in "struct _xmlDict" by SVN
revision#2947
(svn diff -c 2947 http://svn.gnome.org/svn/libxml2/trunk/dict.c).
A global "static xmlRMutexPtr xmlDictMutex" was prefered to this by-dict
mutex in revision#2948
(svn diff -c 2948 http://svn.gnome.org/svn/libxml2/trunk/dict.c).
But the original by-dict mutex is still present in "struct _xmlDict" and
is no more used.
(svn cat -r HEAD http://svn.gnome.org/svn/libxml2/trunk/dict.c)
I've attached a patch that remove this unused mutex.
