The compiler (visual studio) may optimize some explicit strcmp call in openssl source to use the intrinsic memcmp call. In CrtLibSupport.h, we just use #define to mapping memcmp to CompareMem API. So in Link phase, this kind of intrinsic optimization will cause the "unresolved external symbol" error. For example: OpensslLib.lib(v3_utl.obj) : error LNK2001: unresolved external symbol _memcmp This patch will keep the memcmp mapping, and provide extra Intrinsic memcmp wrapper to satisfy the symbol link.
