[PATCH] Fix PR c/9928

- Subject: [PATCH] Fix PR c/9928
Hi,
This is an ICE on illegal code, regression from GCC 3.2.2 present on all
active branches. It appears that my previous patch for PR c/7741 was a bit
gross: http://gcc.gnu.org/ml/gcc-patches/2003-02/msg00641.html
Compiled (this is error-recovery material) and regtested on
i586-redhat-linux-gnu (c 3.2 branch). Ok for mainline and 3.3? Ok for 3.2?
