ok thanks it is defined in the header and in this case they are two bugs.
Try the following program
#include <stdio.h>
typedef __WCHAR_TYPE__ wchar_t;
wchar_t a[] = L"aa";
int s = sizeof(wchar_t);
void main()
{
printf("%i\n",s);
}
under linux it output 4
under linux with -fno-short-char it output 4
under linux with -fshort-char it output 2
under cygwin it output 2
nder linux with -fno-short-char it output 2 (BUG here)
under linux with -fshort-char it output 2
