The default wint_t is "unsigned int", but VxWorks RTPs use "unsigned short"
instead (as they do for wchar_t).  The kernel headers don't provide a
wchar.h header, so there are no compatiblity issues there.

For context, the preceding code is:

   /* VxWorks uses wchar_t == unsigned short (UCS2) on all architectures.  */
   #undef WCHAR_TYPE
   #define WCHAR_TYPE "short unsigned int"
   #undef WCHAR_TYPE_SIZE
   #define WCHAR_TYPE_SIZE 16

Tested on i586-wrs-vxworks, where it fixes gcc.dg/wint_t-1.c.
Ok to install?

ok
