Description:
The implementation of SQLNativeSql casts its last argument (an SQLINTEGER *) to an SQLLEN * when calling copy_lresult. This is bad, because SQLLEN and SQLINTEGER are different sizes on 64-bit platforms.

How to repeat:
Inspect the code.

Suggested fix:
Use a local SQLLEN variable to handle the call to copy_lresult.
