Well, its a fact that that template is defined in stdc++, you can see
that with `nm'.  You can use `ldd' to check if you link with the right
stdc++.  If you are 100% sure that you link (at RUN time) with the correct
library (ie, rename all other libstdc++.* libs to away.libstdc++.*, and
"ldd a.out" shows you link with the correct stdc++ (the one for which
`nm' tells you that your template is defined)) and you still get this
linking error, then I would be surpriced :)

Example:

My custom lib has it undefined too:

~/c++/libr/src/kernel/tests>nm -C /home/carlo/c++/libr/lib/libr.so.0 | grep 'ostream.*smanip<int>'
         U ostream & operator<<<int>(ostream &, smanip<int> const &)

I link with:

~/c++/libr/src/kernel/tests>ldd alarm_tst
        libr.so.0 => /home/carlo/c++/libr/lib/libr.so.0 (0x40000000)
        libstdc++.so.2.9 => /usr/local/egcs-cvs/lib/libstdc++.so.2.9 (0x40065000)
        libm.so.6 => /lib/libm.so.6 (0x400a7000)
        libc.so.6 => /lib/libc.so.6 (0x400c0000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x00000000)

It is defined in:

~/c++/libr/src/kernel/tests>nm -C /usr/local/egcs-cvs/lib/libstdc++.so.2.9 | grep 'ostream.*smanip<int>'
00023854 T ostream & operator<<<int>(ostream &, smanip<int> const &)
