Hello,

The attached patch adds a c.torture/compile test case for PR 53886.
The test case is a slightly modified version of the preprocessed example
in the PR (added forward decls to remove warnings).

Tested on rev 189361 with
make check-gcc RUNTESTFLAGS="compile.exp=pr53886.c 
--target_board=sh-sim\{-m2/-ml,-m2/-mb,-m2a/-mb,-m2a-single/-mb,-m4/-ml,
-m4/-mb,-m4-single/-ml,-m4-single/-mb,-m4a-single/-ml,-m4a-single/-mb}"

without the patch http://gcc.gnu.org/ml/gcc-patches/2012-07/msg00342.html
(fails) and with the patch (passes).

Cheers,
Oleg

Looks OK to me.  I've checked that it passes on i686-pc-linux-gnu
too.
