MFC Link Error - Help/Advice - Emergency $$ will bonus $$ for fast help

We have a statically linkable client library that utilizes MFC. We delivered this library to one of our customers. Our customer requires in their application to over load new and delete operators. For example, see below: void* operator new( size_t size ) { /* some alloc code */ } void* operator new[](size_t size) { /* some alloc code */ } void operator delete( void *ptr ) { /* some dealloc code */ } void operator delete[](void* ptr) { /* some dealloc code */ } Because it seems MFC also does this, there seems to be a conflict with the new/delete operators for MFC and the new/delete operators that are defined in the customers application. When the customer builds it yields the following linker errors: [login to view URL](afxmem obj) : error LNK2005: "void * __cdecl operator new(unsigned int)" (??2YAPAXIZ) already defined in [login to view URL] [login to view URL](afxmem o bj) : error LNK2005: "void __cdecl operator delete(void *)" (??3YAXPAXZ) already defined in [login to view URL] [login to view URL](afxmem ob j) : error LNK2005: "void * __cdecl operator new[](unsigned int)" (??_UYAPAXIZ) already defined in [login to view URL] [login to view URL](afxmem obj ) : error LNK2005: "void __cdecl operator delete[](void *)" (??_VYAXPAXZ) already defined in [login to view URL] We need some advice fast. What can we do to change in our lib code (we cannot remove MFC) to avoid this problem for our customers? We considered building the lib as a dll and telling them to use it that way but it is not ideal. Is there anything we can do with namespaces to avoid this conflict?
