    Dear Sam,
    
    I am trying to convert the TIFF library to late Commodore-Amiga's native
    operating system. Here is a list of things the SAS/C 6.50 compiler was
    unhappy about. I admit that these are mostly cosmetic changes, but I would
    appreciate if I could just compile the sources without any warnings.

Thank you for the comments.  I'll try to look at them soon.  In general
it is most effective to mail me context-style diffs for changes; this
way there is no ambiguity in understanding what modifications are intended
for your system (remember I only have SGI machines).

FYI (though not for you specifically as you provided excellent details on
the problems and fixes), postings of warnings messages from compilers without
associated patches are ignored.

    I have noticed a lot of elaborate code in tif_atari.c handling lseeks past
    the current end-of-file. I'd like to know under what circumstances libtiff
    extends a file in this way because the Amiga I/O system does not allow this
    either. Are the library routines prepared to handle an error return from
    _tiffSeekProc() in this case? I remember the F2C run-time library failing at
    this point :).
    
I didn't write the atari code; it was contributed by alex@falcon.demon.co.uk
(Alex Kiernan).  I don't believe the library will seek past EOF; it should
do explicit writes if it wants to extend an existing file.

    Sam
