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 ;-).
