[PATCH] new gcc.dg/compat tests for _Complex types

[Janis Johnson]

This patch adds four new tests to the C binary compatibility test suite.
These are for passing/returning _Complex types.  For _Complex types
whose real and imaginary parts can be used with va_arg there are tests
with functions having a variable number of arguments.

These have been checked in, after testing on i686-pc-linux-gnu, sh-elf,
powerpc-unknown-linux-gnu, and powerpc64-unknown-linux-gnu.  The patch
itself is attached as a compressed file.
