The Ada compiler now correctly allows formal functions to be defaulted by an expression when core extensions are enabled using the -gnatX flag. Previously, the compiler incorrectly required all extensions to be enabled, which was stricter than intended. The fix modifies par-ch12.adb to pass True for the Is_Core_Extension parameter when calling Error_Msg_GNAT_Extension.
