Which happens to be the case on arm-linux-gnueabi...
The test in gnulib is correct. wchar_t is unsigned int on cygwin as well, and the gnulib test works just fine there, so I suspect the bug is in your system headers, and not in gnulib. What are the values of WCHAR_MIN and WCHAR_MAX? How many bits is unsigned int on arm-linux-gnueabi? - -- Don't work too hard, make some time for fun as well!
