On Linux/PPC there might be a problem with -fPIC code, eg. 
execute/980526-1.c (and 2 other testcase I don't remember right now, but I 
think they were switch/label related too) FAILs execution if compiled with 
-fPIC. I haven't reported yet, because I'm not on my usual known-good build 
environment, but since AIX always uses PIC code, it may be related.

Hope this helps,
Franz.
