- Authentication-results: sourceware.org; auth=none
The fix for PR debug/16063 slightly disturbed the debug info in Ada by adding
bogus base types to enumeration types; the latter are base types in Ada.
Tested on x86_64-suse-linux, applied on the mainline and 5 branch.

* gcc-interface/misc.c (gnat_enum_underlying_base_type): New function.
(LANG_HOOKS_ENUM_UNDERLYING_BASE_TYPE): Define to above.
