Yes, currently TIFF library doesn't have JPEG support (as this libjpeg is
not present in my MSYS environment);
I succesfully built libjpeg, but during tests it reported errors, so I
decided to remove it and then build TIFF without it; In wish list I meant to
add jpeg and its support in tiff.

JPEG support doesn't actually mean anything.

None of the Makefiles use the JPEG variables (JPEGLIB, JPEGLIBPATH and
JPEGINCPATH).

The configure script uses the variables when testing for the TIFF library,
but that only matters if the TIFF library was built with JPEG support but it
requires specific switches to locate the JPEG library (e.g. if the TIFF
library is a static library).

If using --with-tiff and --without-jpeg works, either your TIFF library
doesn't have JPEG support, or it can find the JPEG library without any
assistance. Either way, adding --with-jpeg won't make any difference.
