- Subject: Fix segfault on anonymous structures with -fdump-ada-spec
- Authentication-results: sourceware.org; auth=none
This is a trivial patch to fix a segfault on anonymous structures with the
special -fdump-ada-spec switch. It also contains a fixlet for enumeral types.
Bootstrapped/regtested on x86_64-suse-linux, applied on the mainline.

* c-ada-spec.c (dump_generic_ada_node): Take into account signedness
for enumeral types.
(print_ada_declaration): Add missing guard for record types.

* c-c++-common/dump-ada-spec-7.c: New test.
