Weird.
What happens if you compile with -D_FILE_OFFSET_BITS=64? Does this
cause alpha to have a 64-bit ino_t? (How does that work, exactly?) If
so, then AC_SYS_LARGEFILE should check for this and should arrange for
"#define _FILE_OFFSET_BITS 64".
Matoro, what happens if you compile the following C program?
#include <sys/stat.h>
#include <stdio.h>
int
main (void)
{
int n = sizeof (ino_t);
printf ("%d\n", n);
}
Compile and run it like this:
gcc ino.c
./a.out
gcc -D_FILE_OFFSET_BITS=64 ino.c
./a.out
If the former prints "4" and the latter "8" then we can fix Autoconf
and Gnulib AC_SYS_LARGEFILE to do the right thing.
Also, as Pádraig suggests, the output of the following shell command
would be useful:
strace stat -f -c '%T' .

Although it's about s390x I expect there are similar issues on alpha,
which may not be fixed and if so it's not a coreutils issue per se.
