I had a look, and at first I could reproduce it. _hex__FR3ios (mangled
version of hex() taking an iostream) should be in libstdc++. After
some cleaning up and rebuilding libstdcc+, the error disappeared.

Unfortunately, I don't remember quite what I did.. However, the problem
seems to be that there was an old .o file lying around somewhere. THis
can be a problem, for example, if you have been compiling without obj
dirs, do a 'make obj' without cleaning out all the .o files first.

Apparently, this also happened when the snapshot was built, so the binary
distribution now also has this problem (on 3 different architectures at
least).
