Hi,

I found the bug in the configure script when I executed it for building tiff-3.7.0.

The '--disable-old-jpeg' configure option does ENABLE "Old JPEG support"! This option '--disable-old-jpeg' should have disabled "Old JPEG support" regardless of the default.

The following patch fixes this problem:

 # Check whether --enable-old-jpeg or --disable-old-jpeg was given.
+HAVE_OJPEG=no
 if test "${enable_old_jpeg+set}" = set; then
   enableval="$enable_old_jpeg"

----------(cut here)----------

The option '--disable-old-jpeg' sets ${enable_old_jpeg} "no", therefore the condition

        test "${enable_old_jpeg+set}" = set
becomes 'true', NOT 'false'.
