+
+ * exp_ch4.adb (Expand_N_Op_Eq): The frontend assumes that we can
+ do a bit-for-bit comparison of two access to protected
+ subprogram pointers. However, there are two reasons why we may
+ not be able to do that: (1) there may be padding bits for
+ alignment before the access to subprogram, and (2) the access to
+ subprogram itself may not be compared bit-for- bit because the
+ activation record part is undefined: two pointers are equal iff
+ the subprogram addresses are equal. This patch fixes it by
+ forcing a field-by-field comparison.
+ * bindgen.adb (Gen_Adainit): The type No_Param_Proc is defined
+ in the library as having Favor_Top_Level, but when we create an
+ object of that type in the binder file we don't have that
+ pragma, so the types are different. This patch fixes this issue.

+ access to protected subprogram is two addresses. We need to
+ create the same record that the compiler makes to ensure that
+ any padding is the same. Then we have to look at just the first
+ word of the access to subprogram. This patch fixes this issue.
