Turns out to be a piece of cake, actually. It seems each compiler has its own way of letting you know it's building 64-bit code. In the case of Sun's Forte, it defines '_LP64'. I started with a freshly undone tiff-v3.6.1.tar.gz, changed line 82 of tiff.h to read:

#if defined(_LP64) || defined(__alpha) || (defined(_MIPS_SZLONG) && _MIPS_SZLONG == 64) || defined(__LP64__) || defined(__arch64__)

Put my 64-bit "site.config" (see attached) in place, and got a clean, WORKING build. I did have to re-build gtk/gdk_pixbuf to get the tiff loaders to work correctly, but they're working 100% now, too.

Side note - it seems that for every 64-bit platform and for every compiler on those platforms, there's a different, vendor-specific set of defines that happen when using the compiler in 64-bit mode. Since the 64/32 bit issue in this case (libtiff) comes down to a single type - uint32 - would it be possible, rather than using the messy sequence of if defined()'s above, that a known 32-bit on all platform type be used to typedef uint32? This has to be possible, somehow, right?

I've been building code like a madman, both 32 and 64 bit for every package, for the past couple of weeks getting my package arsenal up to date, and so far at least 80% of them haven't required any code changes to build cleanly, only configure options.

Just looking for a possibly more elegant solution than my stuck-on fix above.

Ok, I'll work on this one tonight if possible.

I'll try to get to this after I grab a backtrace on tiff2pdf.

# Configuring supporting libraries.
#
# The TIFF software makes use of two ancillary packages: the IJG
# distribution to support the JPEG codec and the zlib distribution
# to support the Deflate codec.  To setup use of these packages you
# need to specify where each package's include files are located and
# where the pre-built library (static archive or DSO) is located.
# These may be different or the same (as when the package is compiled
# and referenced directly from the place where the software was
# loaded and compiled).
#
# DIRS_LIBINC is a space-separated list of directories to use for
# locating include files in these packages.  Note that it should not
# include -I options as might be passed to the C preprocessor; these
# are automatically added by the configure script when the Makefiles
# are generated.
#
# DIR_<package>LIB is the pathname of the directory where <package>'s
# pre-built library may be found; this is used when building a TIFF
# DSO (on systems where support is present) and when building the
# programs in the tools directory.  By default the configure script
# will load the associated library using
#
#     -L${DIR_<package>LIB} -l<package>
#
# e.g. -L${DIR_JPEGLIB} -ljpeg.  If this is wrong for your system
# (e.g. your compiler/loader does not support the -L option), then
# the LIB<package> parameter can be set explicitly to specify the
