2004.09.10 05:19 "tiffconf.h defunct?", by Bob Friesenhahn

Past versions libtiff have included a tiffconf.h header which provides 
oodles of _SUPPORT defines so that client applications can see what 
features are provided in the library.  For example, if CCITT_SUPPORT 
is defined, then CCIT FAX compressionis supported.  I discovered that 
this was missing in the CVS/alpha version when I noticed that features 
of GM's TIFF support were silently missing.

While these defines were also used to configure the library, portable 
applications also use them to decide how to best use the library.

If an equivalent set of _SUPPORT defines is not provided by the 
configure-based build environment, many significant applications will 
silently break.
