[PATCH/RFA] SH: Avoid warnings when building

[Kaz Kojima]

Hi,

I've checked in the patch
<URL:http://gcc.gnu.org/ml/gcc-patches/2004-06/msg02243.html>
on mainline which was pre-approved by Alex.  Sorry for the delay.
A few temporary problems on mainline have prevented bootstrapping
on sh4-unknown-linux-gnu target.  Now it's tested successfully with
bootstrap/regtest on mainline for that target.

Regards,
