Re: Compiling fileutils 4.1 with OS/2

[Andreas Buening]

Hello!

The most tools are currently working. However, I have to find out, how
to
recognize mounted file systems to be able to compile df.
Some won't work like ln, sync, mknod, mkfifo.


The current changes to aclocal.m4:

I've used the following construct to handle non existing functions:

#if !HAVE_LINK && !defined link
static int
link (const char *oldpath, const char *newpath)
{
  errno = EPERM; /* file system does not support creation of hard links
*/
  return -1;
}
#endif


I also have a question: Is it convenient to change the lib/*.c files or
is it
better to restrict all changes to src/*.c?


bye,
Andreas
