[PATCH] Fix PR optimization/8275

[Eric Botcazou]

Hi,

This is a regression from gcc 3.0.x on gcc-3_2-branch, which was fixed on 
mainline by:

http://gcc.gnu.org/ml/gcc-patches/2002-09/msg01150.html

Bootstrapped/regtested on i586-redhat-linux-gnu (c,c++,objc,f77).
OK to commit ? OK to install the testcase on mainline as well ?
