>Description:
locale::_Impl::_Impl was recently modified in the context
of the Posix names work (see 2002-10-16 commits). However, unfortunately, strtok is *not* thread-safe.
This is a regression wrt the much limited but thread-safe
implementation present in 3.2. 
>How-To-Repeat:

>Fix:
Already fixed in mainline. See 2002-11-25 and 2002-11-28
commits.
