Ok, I got it. The name format is defined as ANON_AGGRNAME_FORMAT.
The function responsible for naming anonymous structs/unions is
make_anon_name().

Use TYPE_ANONYMOUS_P() to check for anonymous structs/unions:

#include "cp/cp-tree.h"

RECORD_OR_UNION_CODE_P(TREE_CODE(node)) && TYPE_ANONYMOUS_P(node))


I hope my monologues on the GCC lists are useful to someone ;-).
