[boost] [regex] Link problem with VC8 regex build

Hi,

I have built the regex library as per instructions, using a command
prompt set up by Visual Studio.  When I come to build my project using
the library, it automaticaly pulls in the regex lib file, but I get
multiple defined symbols from the linker:

Linking...
libboost_regex-vc80-mt-gd-1_33_1.lib(usinstances.obj) : error LNK2005:
"public: static unsigned int __cdecl std::char_traits<unsigned
short>::length(unsigned short const *)"
(?length@?$char_traits_at_G@std@@SAIPBG_at_Z) already defined in
msvcprtd.lib(MSVCP80D.dll)
libboost_regex-vc80-mt-gd-1_33_1.lib(usinstances.obj) : error LNK2005:
"public: __thiscall std::allocator<unsigned short>::allocator<unsigned
short>(void)" (??0?$allocator_at_G@std@@QAE_at_XZ) already defined in
msvcprtd.lib(MSVCP80D.dll)

My app is built with wchar_t as unsigned short, and with UNICODE and
_UNICODE defined, so I updated the makefile for this and rebuilt, but I
just get the same thing.

I can't even see how usinstances.cpp or any other file defines these
things, and searching boost and the web reveals nothing.  Any ideas,
anyone?

Thanks,

Simon
