 * Added parenthesis around n in H245ASSERT() macro.
 * Note: Logical not (!) has higher operator precedence than equal/not equal
 * (== or !=). Therefore, in many places this ASSERT was not acting as the
 * author intended. It is always a good idea to fully parenthesize expressions
 * in macros!

 * 
 * - Added export InstanceTbl to module.. from h245init.x
