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.
