Is that even posix compat?
Yes, it is posix compatible to have wint_t be unsigned. Not only that, but both glibc (32-bit wchar_t) and cygwin (16-bit wchar_t) use a 32-bit unsigned int for wint_t. Any code that expects WEOF to be less than 0 is broken. -- Eric Blake ebl...@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
