Problems with Data Types, Low Severity (4)

	Change	Effect
1	Base type of field function has been changed from *int()() to int()(int,int)*.	Replacement of field base type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Base type of field function has been changed from *int()() to int()(int,int)*.	Replacement of field base type may indicate a change in the semantic meaning of the field.
2	Field name became const.	The value of this field is expected to be const in new library version, but can be modified by old applications.
3	Type of field name has been changed from char* to char const*.	Replacement of the field data type may indicate a change in the semantic meaning of the field.
