Not very well, at least not in mysql 5.0.45:

mysql> select * from t limit -2;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-2' at line 1
mysql> select * from t limit 2 offset -2;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-2' at line 1

This behavior suggests that they can't even deal with LIMIT/OFFSET
values that aren't simple integer literals ...
