Hi Alexandre,

I've created a test toolchain for you on the GCC compute farm: 
gcc14.fsffrance.org

Please see /home/ams_cs/gccobj and /home/amd_cs/install.

I ran "make check RUNTESTFLAGS=pch.exp" already, so you should be able 
to see the errors in gcc/testsuite/gcc/gcc.log.

The sources and objects are set world writeable, so you should be able 
to experiment (please set "umask 0" so I can clean up after).
