1) Environment is x86, Fedora Core 5, gcc (GCC) 4.1.1 20060525 (Red Hat 
4.1.1-1)


2) I rebuild it with --disable-werror and it works fine. Testsuite looks 
good:
http://sources.redhat.com/ml/gdb-testers/2006-q4/msg00023.html


3) I switched the environment so you get the error msg in english. Sorry 
for the german :-) So this is for x86 without --disable-werror
