Bug: MSVC uses intrinsic versions of ceil and floor for floating-point modes precise and fast (diagnosed)

You've got your finger on it.  It suffices to get<code>
  #pragma function(ceil, floor)
</code>into the sqlite3.c compilation before the address of either "function" is taken. Then, whether SQLITE_DISABLE_INTRINSIC is #define'd or not, those 3 errors vanish.
