See

http://sources.redhat.com/ml/libc-alpha/2004-01/msg00232.html

Should I apply

http://sources.redhat.com/ml/binutils/2004-02/msg00066.html

I got

[hjl@gnu-10 tmp]$ /usr/gcc-4.0/bin/gcc -O2 x.c
x.c:2: warning: \uffff\uffff\uffff__libc_errno\uffff\uffff\uffff
aliased to undefined symbol \uffff\uffff\ufffferrno\uffff\uffff\uffff
