Where are opfx(), osfx(), ipfx()?

[Craig Rodrigues]

Hi,

I am trying to compile some third party code which wants
to use ostream::opfx(), ostream::osfx(), istream::ipfx() functions.
These functions appear to be in libstdc++-v2, but not in libstdc++-v3
(at least not in: gcc version 3.0 20010223)

Where are they?
If they are deprecated functions, how can I port this old code
to use the libstdc++-v3 equivalents?

Thanks.
