The following simple program fails to compile on FreeBSD 5.4:
#define _POSIX_C_SOURCE 1
#include <iostream>
g++ issues the following error message:
/gcc-current/bin/../lib/gcc/i386-unknown-freebsd5.4/4.1.0/../../../../incl
ude/c++/4.1.0/cwchar:166:

The FreeBSD 5.4 system compiler, which basically is GCC 3.4.2, has the
same issue.
