Summary: Allow passing of anonymous aggregates when signature
matches
Product: gcc
Version: 4.4.5
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: c
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: robert.staudinger@gmail.com

anon-aggregate-stack.c
It would be nice if GCC allowed passing of anonymous aggregates if their
signatures match.
Currently, judging from the error message, it seems like no attempt is being
made at finding out if the anonymous types would match.
anon-aggregate-stack.c:15: error: incompatible type for argument 1 of ‘f’
anon-aggregate-stack.c:6: note: expected ‘struct <anonymous>’ but argument is
of type ‘struct <anonymous>’
