Without an error message or further analysis as to why the 'T.37 gateway'
rejects the TIFF file, we cannot work on this.

Note that the 8.71 changes to use 'libtiff' with a default MaxStripSize=8192,
so if the T.37 gateway cannot handle multi-strip TIFF files (as some fax
software cannot) this may be the source of the error (just a guess).

Multi-strip TIFF files are part of the TIFF spec and any reader that cannot
handle them is flawed.

To revert to the 8.70 behavior, try -dMaxStripSize=0 (unlimited strip size,
so only a single strip will be produced per page). This can also be built
into the binary by changing base/gdevtifs.h line 53 from:
#define TIFF_DEFAULT_STRIP_SIZE 8192
  to
#define TIFF_DEFAULT_STRIP_SIZE 0

and rebuilding. If this is the issue, it is a duplicate of bug 691166
   http://bugs.ghostscript.com/show_bug.cgi?id=691166

Resolving as INVALID for now until the problem with the T.37 gateway can be
identified.

If it is not the multi-strip issue described above, please re-open this bug.
