/*
* the FreeBSD libc uses UCS4, but libstdc++ has no proper wchar_t
* support compiled in:
* http://gcc.gnu.org/onlinedocs/libstdc++/faq/index.html#3_9
* And we are not interested at all what libc
* does: What we need is a 32bit wide wchar_t, and a libstdc++ that
* has the needed wchar_t support and uses UCS4. Whether it
* implements this with the help of libc, or whether it has own code
* does not matter for us, because we don't use libc directly (Georg)
