Link errors

We're frequently running into these linkage errors and haven't been able to track the problem down.  If anyone else has run into this and solved it, we'd sure like to know.  A couple of us here have already checked the obvious....all our libraries are compiled multi-threaded.  The project links fine under RELEASE, but fails under DEBUG.

Linking...
nafxcwd.lib(afxmem.obj) : error LNK2005: "void * __cdecl operator new(unsigned int)"(??2@YAPAXI@Z) already defined in LIBCMTD.lib(new.obj)
nafxcwd.lib(afxmem.obj) : error LNK2005: "void __cdecl operator delete(void *)"(??3@YAXPAX@Z) already defined in LIBCMTD.lib(dbgdel.obj)
LINK : warning LNK4098: defaultlib "LIBCMT" conflicts with use of other libs; use /NODEFAULTLIB:library
LINK : warning LNK4098: defaultlib "nafxcw.lib" conflicts with use of other libs; use /NODEFAULTLIB:library

Sometimes, we're able to delete the project files and rebuild them from scratch and that will fix it.  We've done compares on the .MAK files and haven't seen anything significantly different.

I think this is a problem with the order default libraries are linked. I had similar problem with other libraries. I don't know what is the reason but you can try a workaround that worked for me. Put LIBCMTD.lib (or nafxcwd.lib, I can't recall which one it was) in *both* 'Ingnore Default Libraries' (or whatever it is exactly called) and 'Use libraries' edit boxes in Link section(General subset I believe) of project settings. I'm sorry that I can't be more specific but I don't have DevStudio here.
