Which broken systems? Certainly not on FreeBSD or Linux. A little test:
#include <sys/types.h>
#include <sys/stat.h>
#include <stdio.h>
int main(void) {
struct stat sb;
stat("/home/rasmus/foo/u2.inc",&sb);
printf("%d:%d\n",sb.st_dev, sb.st_ino);
}
That ends up doing just a single stat on FreeBSD:
stat("/home/rasmus/foo/u2.inc",0x9fbffa0c) = 0 (0x0)
and on Linux:
stat64("/home/rasmus/foo/u2.inc", {st_mode=S_IFREG|0644, st_size=12, ...}) = 0
