Since I updated 'mamba' to NetBSD 11 (which has gcc 12.5.0),
it's been spewing a closely related warning:

parse_func.c: In function 'LookupFuncWithArgs':
parse_func.c:2457:15: warning: 'argoids' may be used uninitialized [-Wmaybe-uninitialized]
2457 | oid = LookupFuncNameInternal(func->args_unspecified ? objtype : OBJECT_ROUTINE,

parse_func.c:2395:33: note: 'argoids' declared here

Presumably this could be silenced in the same way as in f04781df5.
I haven't troubled so far because I don't see any other BF animals
producing the same warning, but perhaps we should silence this one
too?
