Copyright (C) 2005 Free Software Foundation, Inc.

Compiled by GNU CC version 4.0.1 20050727 (Red Hat 4.0.1-5).
Compiled on a Linux 2.4.20 system on 2005-11-01.

The following test program shows invalid behavior:
#include <sys/statvfs.h>
#include <stdio.h>

void print(struct statvfs value)
{
         printf("%ld\n", (long)value.f_bavail);
}

int main(int argc, char*argv[])
{
         struct statvfs st;
         if(argc!=2){
                 printf("usage: checkstat <path>\n");
                 return 1;
         }
         statvfs(argv[1], &st);
         print(st);
}

falk@juist:/tmp% gcc -D_FILE_OFFSET_BITS=64 test.c && ./a.out /

The problem seems to be that ./sysdeps/unix/sysv/linux/alpha/bits/typesizes.h is
different from ./sysdeps/generic/bits/typesizes.h and defines
__FSBLKCNT_T_TYPE, __FSBLKCNT64_T_TYPE, __FSFILCNT_T_TYPE, __FSFILCNT64_T_TYPE
macros as 32 and 64 bits. I guess the glibc is build with 32 bits
(__FSBLKCNT_T_TYPE, __FSFILCNT_T_TYPE) by default.

What is the correct way to fix it? To define above macros the same way as it is
done in generic version?

Thank you
