 Hi,
 
 Following patch addresses PR 4536 on mainline.
 
 "ostream's seekp and istream's seekg methods need to use failbit as
 `ios_base::failbit'.
 It may be worth noting that the setting of failbit goes in line 
 with the change for library DR #129. The standard pre-DR edits 
 does not include the clause in $27.6.2.4(2) regarding the setting 
 of failbit."
 
 
 2001-10-11  Brendan Kehoe  <brendan@zen.org>
 
 	* bits/ostream.tcc (seekp): Scope use as ios_base::failbit.
 	* bits/istream.tcc (seekg): Likewise.
