statvfs() system call fails with errno 88 in SUA 6.1

hello,

encountered problem statvfs() system call in sua 6.1 (windows server 2008 r2 64-bit, sua sdk version november 2010). returns errno 88 (value large stored in data type).

following program illustrates problem (compile gcc):

  #include <fcntl.h>  #include <sys/statvfs.h>  #include <stdio.h>  #include <errno.h>  #include <string.h>    int main(int argc, char* argv[])  {    struct statvfs statvfsdata;    int rc = statvfs("/dev/fs/c/", &statvfsdata);      if(rc != 0)    {      printf("error statvfs(): errno = %d (%s)\n", errno, strerror(errno));      switch( errno )      {        case eoverflow:          printf("eoverflow: file size in bytes or number of blocks allocated file or file serial number cannot represented correctly in structure pointed buf.\n");          break;      }      exit(1);    }    printf("fs id = %d\n", statvfsdata.f_fsid);  }  

output of program is:

$ ./a.out  error statvfs(): errno = 88 (value large stored in data type)  eoverflow: file size in bytes or number of blocks allocated file or file serial number cannot represented correctly in structure pointed buf.

running truss shows system call problem:
