Hi Folks,

I am getting the following warnings when building libtiff on 64 bit Ubuntu
with a C++ project with g++ warning level turned up:

/home/aaron/src/grok/thirdparty/libtiff/tif_dirread.c: In function

I am trying to reduce volume of warnings on my project, so if someone has
the time to take a look at these, would be greatly appreciated!

Cheers,
