[Boost-users] linker problems with gcc 3.3.5 and 3.4.3

Hi, I've recently started getting thousands of messages like the 
following, while linking with -lboost_regex -lboost_date_time 
-lboost_filesystem.

/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5/../../../../i686-pc-linux-gnu/bin/ld: 
`.gnu.linkonce.t._ZN5boost2io6detail22parse_printf_directiveIcSt11char_traitsIcEN9__gnu_cxx17__normal_iteratorIPKcSsEENS0_16basic_outsstreamIcS4_EEEEbRT1_RKSC_PNS1_11format_itemIT_T0_EERT2_h' 
referenced in section `.rodata' of monotone-commands.o: defined in 
discarded section 
`.gnu.linkonce.t._ZN5boost2io6detail22parse_printf_directiveIcSt11char_traitsIcEN9__gnu_cxx17__normal_iteratorIPKcSsEENS0_16basic_outsstreamIcS4_EEEEbRT1_RKSC_PNS1_11format_itemIT_T0_EERT2_h' 
of monotone-commands.o

Linking monotone (http://www.venge.net/monotone) produces ~5000 or so 
messages like this. I'm running on gentoo linux and I believe this 
started happening when I recently upgraded from gcc 3.3.4 to 3.3.5.

Originally I was using boost 1.31.0 but I have tried upgrading to 1.32.0 
and also upgrading gcc to 3.4.3. I have not yet tried downgrading gcc to 
3.3.4 but that's pretty much next on the list.

I really don't know for sure what is causing this, but it really is 
quite annoying. It could be gentoo's packaging of gcc or something else, 
or it could be gcc or boost, or ...

I do see a few similar sounding posts such as 
http://www.mail-archive.com/[e-mail]/msg74258.html but so 
far haven't been able to fix the problem.

Any help or insight would be greatly appreciated.

Cheers,
Derek
