readlink on AIX 7.1BETA

[Bruno Haible]

Hello Rainer,

Regarding this failure:

  test-readlink.h:54: assertion failed
  FAIL: test-readlink

Could you please show what is the value of errno between these ASSERT 
statements:

  ASSERT (func (BASE "file/", buf, sizeof buf) == -1);
  printf ("errno = %d\n", errno); perror ("errno was"); /* INSERT THIS LINE */
  ASSERT (errno == ENOTDIR);

Depending on this value, we may want to either change the autoconf test for
readlink, or change the test.

Bruno
