I incorrectly diagnosed the problem. The error I sent was
common to gcc-2.95 and gcc-3.2. The problem occurs if the windows
loader libraries in /usr/lib/octave-2.1.40 are stripped
( as in make install-strip ).

Note that the various dll's and the octave executable can be
stripped without issue.

Example:
address@hidden /usr/src/octave-2.1.40-dynlink/examples
$ mkoctfile hello.cc

$ strip /usr/lib/octave-2.1.40/*.a
$ mkoctfile hello.cc
hello.o(.text+0x14e): In function `FShello_gnu_v3':
/usr/include/c++/3.2/bits/stl_alloc.h:630: undefined reference to
`check_version (std::basic_string<char, std::char_traits<char>, ...

There are still some gcc-2.95 problems. I will send those in a
separate message (because they're on another machine)
