Problems with Data Types, Low Severity 4

	Change	Effect
1	Size of this type has been changed from 8792 bytes to 8840 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 56 bytes to 64 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 4 bytes to 8 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Base type has been changed from long to long long.	Replacement of the base data type may indicate a change in its semantic meaning.
