llvm dev - Jul 2004 - [LLVMdev] AsmWriter.cpp:255: error: ambiguous overload for `std::basic_ostream<char,...

Yes, Chris you're right. It seems that my << operator for int64_t is
missing
in my '/opt/gcc.3.3/include/c++/3.3/bits/ostream.tcc' file.

Which ordinary version of GCC are you working with and how do your 
definition of the << operator for int64_t look like?

We've used versions of G++ from 2.95 (which probably doesn't work with
LLVM now) through 3.4.  All of them had working operator<<'s.  My
guess
is that the internix port is broken somehow.  I'm sorry, but I don't
know
anything about the internix port.  You could ask on the
gcc-help at gcc.gnu.org mailing list, as they are probably the right ones to
ask.
