Is this the correct return value when trying to create a directory
that exists?  Linux returns EEXIST while DJGPP returns EACCESS.   I
notice that DOS returns permission denied, too.  Is this a limitation
of the error codes that DOS returns from system calls?

I wrote a simple little test routine to check this:

------------------------------------------------------------------------

#include <unistd.h>  /* Comment this out for a DOS compiler */
#include <stdlib.h>
#include <stdio.h>
#include <errno.h>

main ()
{
  char sz[80];
  int result;

  printf ("Directory to create:");
  scanf ("%s", sz);
  printf ("errno before %d (%s)\n", errno, sys_errlist [errno]);
  result = mkdir (sz, 0777);
  printf ("errno after %d (%s) with %d return\n", errno, sys_errlist [errno],
	  result);
  exit (0);
}
