B20: bash does not like CRLF on stdin

[Anton Leherbauer]

Create from the command line:

	C:> echo ls > foo.sh
	C:> bash foo.sh
	    ... lots of output ...
	C:> bash < foo.sh
	: No such file or directory

The problem is that bash treats stdin as binary, thus leaving the
CR/LF in place. Interestingly, the following experiment works:

	C:> bash
	bash-2.0$ bash < foo.sh
	    ... lots of output ...

This happens with cygwin B20 and bash 2.03 and is
especially bad, when using bash together with clearmake,
because clearmake executes build scripts in the above manner.

Jim Chapman [jim.chapman@xstreamis.com]
provided me with a fix to the problem:

Edit make_cmd.c in function make_bare_word() near line 53 (version is 2.02).
Make it look like
-------------------------------- begin ----------------------------
make_bare_word (string)
     char *string;
{
  WORD_DESC *temp;

  temp = (WORD_DESC *)xmalloc (sizeof (WORD_DESC));
  if (*string)
  {
    /* JC. Remove any rogue carriage return char - 12/21/98. */
    int j, slen;
    slen = strlen(string);
    if (string[slen-1] == 0x0d)
    {
      string[slen-1] = '\0';
    }
    
    temp->word = savestring (string);
  }
  else
    {
      temp->word = xmalloc (1);
      temp->word[0] = '\0';
    }

  temp->flags = 0;
  return (temp);
}
--------------------------------- end -------------------------------

It would be great, if the fix would get into the common distribution.

Thanks,
Toni
