+Subject: [PATCH] * libtiff/tif_fax3.h: revert change done on 2016-01-09 that
+ made Param member of TIFFFaxTabEnt structure a uint16 to reduce size of the
+ binary. It happens that the Hylafax software uses the tables that follow this
+ typedef (TIFFFaxMainTable, TIFFFaxWhiteTable, TIFFFaxBlackTable), also they
+ are not in a public libtiff header. Raised by Lee Howard. Fixes
+ http://bugzilla.maptools.org/show_bug.cgi?id=2636
