Could this change be merged down to the 4.3 branch? Currently 4.3.2 release is
still broken.

For what it's worth, I just wanted to add a me too. I'm building on Solaris 9
sparc using gcc 4.2.4 to build with. The error occurs with 4.3.1 and the
20080724 snapshot.

[Bug c/18786] New: gcc tests fail in gcc.dg/duff-2.c

[tim at bishnet dot net]

gcc test suite fails:

FAIL: gcc.dg/duff-2.c (test for excess errors)

In the log file:

Excess errors:

I notice this bug has been reported before, and closed as fixed. I'm using the
latest in the 3.3 branch, so I would have expected it to be fixed here too.
