- Subject: Define wint_t for VxWorks
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?
