Dear Claus-Peter Knaut,

the 'stat' and 'lstat' functions are standard UNIX system calls,
that are used to get information about files.
From the man-pages:

STAT(2)             Linux Programmer's Manual             STAT(2)


NAME
       stat, fstat, lstat - get file status

SYNOPSIS
       #include <sys/stat.h>
       #include <unistd.h>

       int stat(const char *file_name, struct stat *buf);
       int fstat(int filedes, struct stat *buf);
       int lstat(const char *file_name, struct stat *buf);

DESCRIPTION
       These  functions  return  information  about the specified
       file.  You do not need any access rights to  the  file  to
       get  this  information  but  you need search rights to all
       directories named in the path leading to the file.
....


if these are missing in the link phase, then either something is
wrong with your linux set-up, or the (modified) link-directive
generated by the compiler does not work in your case.

The solution mentionmed in the FAQ is known to work with the
Slackware distributions, whereas some problems have been reported for
Redhat distributions. What linux distribution do you use?

Can you link a C program, that uses lstat?

Please note, that as of the forthcoming release 4.0 of the Mjolner
BETA System, the linux compiler will generate linux ELF files
directly, and will not require modifications to the link-directive to
work.

Sincerely,

Peter Andersen
