I think x86 treats char as unsigned, in which case 14600 would not
apply.
No.
$ cat test.c
#include <stdio.h>
int main()
{
char x = -1;
unsigned char y = -1;
printf("%d %d\n", (int)x, (int)y);
return 0;
}
$ cc test.c
$ ./a.out
-1 255
So 14600 should apply.
Agree. C has both signed char (default) and unsigned char. Should have
been byte, but oh well.
