Before libtiff got a configure script, it was normal for the features 
of each libtiff to be different.  As a result, applications included 
tiffconf.h and tested for feature support via the *_SUPPORT defines.
There are many useful applications which use libtiff but which are no 
longer actively maintained.  Without supporting this legacy usage, 
these old applications will fail to compile.  Even many current 
applications will use this header since they want to continue working 
with anchient libtiff as well.
