Description:
On the page 

  http://dev.mysql.com/doc/mysql/en/C_API_Prepared_statement_datatypes.html

MYSQL_TYPE_LONG is documented to have 'long int' as the corresponding C type.
On another place in the manual MYSQL_TYPE_LONG is documented to be 4 bytes.

Most 64 bit systems let 'int' to be 4 bytes and 'long int' to be 8 bytes. The
corresponding C type that is 4 bytes on both 32 bit and 64 bit systems is
then 'int', not 'long int'.

How to repeat:
This is a documentation bug.

The only thing that we can say is that MYSQL_TYPE_LONG is a typecode for 4-byte host language type.
Currently there is no system we have binaries for, where sizeof(int) != 4
So yes, despite that the name is a bit misleading, corresponding C type is int;
long suits only on 32-bit machines.
