[PATCH] new tests for gcc.dg/compat: fnptr, attributes
- From: Janis Johnson <janis187 at us dot ibm dot com>

- Subject: [PATCH] new tests for gcc.dg/compat: fnptr, attributes
This patch adds three new tests to the C binary compatibility test suite,
to check passing function pointers as arguments, and to check layout
compatibility for structs that use packed and alignment attributes.
It's been committed.
