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:

 fi;

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

        test "${enable_old_jpeg+set}" = set

becomes 'true', NOT 'false'.
