This error does not occur with the version of gcc in CVS.
You may wish to upgrade your compiler (2.96-74 is the latest from Redhat).

If you do:
rpm -ql libstdc++
rpm -ql libstdc++-devel

This will list the libraries and header files that came with your
Redhat distribution of the Standard C++ library.  It looks
like the Redhat distribution does not come with <ios>, but
it does come with <iosfwd>.  You can try that.

For general C++ questions, it is best to post them to the newsgroup
comp.lang.c++.moderated.
