Already defined symbol (void * __cdecl operator new(unsigned __int64,void *) when using libmemcached

Question

I'm creating and using libmemcached with Visual Studio. Since we have updated the compiler version operator new and new [] are defined in that library and I get errors when linking a DLL.

dumpbin /symbols microsoft_net_16_YlibmemcachedD.lib | grep new
1E4 00000FA6 SECT5F notype       Label        | $yynewstate$991

When using the new library I'm getting errors:

When using the option "LDFLAGS += /FORCE:MULTIPLE" it works. But I'm not sure whether this is a good solution. Any hints?
