LNK2001 error after upgrade to VS2008 and XP64 from VS2005 and XP32

I have a Win32 DLL project which builds perfectly on my VS2005(pro) machine running XP32(pro). On a newer machine with VS2008(standard)  running XP64 the same code fails to link with the following errors:

asl.lib(AAFAlgorithm2.obj) : error LNK2001: unresolved external symbol "unsigned int (__stdcall* ATL::g_pfnGetThreadACP)(void)" (?g_pfnGetThreadACP@ATL@@3P6GIXZA)
...
asl.lib(AAFInfo.obj) : error LNK2001: unresolved external symbol "unsigned int (__stdcall* ATL::g_pfnGetThreadACP)(void)" (?g_pfnGetThreadACP@ATL@@3P6GIXZA)

where asl.lib is a third-party 32bit library.
I can register the successfully built DLL on the newer machine and it works fine, but I can't seem to build it on the newer machine. I don't know if this is a XP32-XP64 issue, or a VS05-VS08 issue. I've read a lot of advice from the internet about these LNK2001 errors, but nothing has worked yet. I'm open to all suggestions no matter how obvious they may seem.

Thanks

Unforunately, g_pfnGetThreadACP is removed from VS2008.  Since you say asl.lib is third party, you'll need to keep building with VS2005, get a newer version of the third party library that is built with VS2008, build a custom version of ATL, or modify the third party source code yourself if that is an option.

Look at the differences between the two version of atlconv.h at the
 "#if(n)def _CONVERSION_DONT_USE_THREAD_LOCALE"
to see the differences.  Logic was greatly simplified in VS2008 and g_pfnGetThreadACP was obsoleted.

Since it looks like you are building the third party library, you could just change the call or replicate the old g_pfnGetThreadACP  function in a library of your own and add the new library to the link dependency list of the third party library.

It's a big relief to confirm this isn't an XP64 issue.
I will keep working with VS05 until our vendor provides a new library.

Thanks
