>Description:
FreeBSD's <wchar.h> needs to define WCHAR_MIN and WCHAR_MAX.
After discussions with Mike Barcroft, I submitted PR 50523
( http://www.freebsd.org/cgi/query-pr.cgi?pr=50523 ) to deprecate
<machine/limits.h> and create a private header <machine/_limits.h> and
a public header <sys/limits.h>.  After the patch 50523 is applied,
then this patch can be applied to define WCHAR_MIN and WCHAR_MAX in <wchar.h>
