<pre>Test program:
#include <pthread.h>
class X {
using AnonUnionTypedef = pthread_mutex_t;
AnonUnionTypedef u;
} x;
(gdb) pi gdb.lookup_type('X::AnonUnionTypedef').strip_typedefs().name is None
True
Conversely if I compile with g++:
(gdb) pi gdb.lookup_type('X::AnonUnionTypedef').strip_typedefs().name
'pthread_mutex_t'</pre>
