[Image-SIG] PIL 1.1.1 Problem with Windows NT, Python 1.5.2

[Roger Burnham]

Using VC++ 6.0 (no service packs) and Python 1.5.2.

Got it to build (after undef'ing INT32 and UINT32 before including windows.h).

Now, 

>>> import Image
>>> img = Image.open(r'C:\TMP\160x160.jpg')
>>> img.size
(160, 120)
>>> img.getpixel((10,10))
(64, 74, 73)
>>> img.save('c:/tmp/fred.jpg')
Traceback (innermost last):
 File "<interactive input>", line 0, in ?
 File "C:\Python\Imaging\Image.py", line 674, in save
   SAVE[string.upper(format)](self, fp, filename)
 File "C:\Python\Imaging\JpegImagePlugin.py", line 307, in _save
   ImageFile._save(im, fp, [("jpeg", (0,0)+im.size, 0, rawmode)])
 File "C:\Python\Imaging\ImageFile.py", line 368, in _save
   s = e.encode_to_file(fh, bufsize): (0, 'Error')

Running under the debugger, tracing into _encode_to_file (encode.c), at the line

   if (write(fh, buf, status) < 0) {

I step into _write and trip over

        if ( ((unsigned)fh >= (unsigned)_nhandle) ||
             !(_osfile(fh) & FOPEN) )
        {
                /* out of range -- return error */
                errno = EBADF;
                _doserrno = 0;  /* not o.s. error */
                return -1;
        }


here, fh = 4, _nhandle = 32.

MSDN says:

EBADF
Bad file number. There are two possible causes: 1) The specified file handle is 
not a valid file-handle value or does not refer to an open file. 2) An attempt 
was made to write to a file or device opened for read-only access.

Anyone offer any clues???
