Description of Problem:

Hello there,

I just tried to compile package libtiff-3.5.7-7 from Redhat 8.0.

Here are some of the compiler messages.

../tools/fax2tiff.c:77: warning: `whandler' might be used uninitialized in this
function
../tools/ppm2tiff.c:61: warning: `photometric' might be used uninitialized in this function
../tools/ppm2tiff.c:67: warning: `spp' might be used uninitialized in this function
../tools/tiff2ps.c:948: warning: `breaklen' might be used uninitialized in this
function
../tools/tiffmedian.c:406: warning: `first' might be used uninitialized in this
function
../tools/tiffmedian.c:406: warning: `last' might be used uninitialized in this function
../tools/tiffset.c:89: warning: too few arguments for format
../tools/tiffset.c:115: warning: too few arguments for format

Here is a patch which fixes the messages.
