title: xcode build error: " Conflicting types for 'uint64' " makes no sense to me
body: <p>I am not a regular programmer, but of necessity.  I am using the tiff-4.0.3 as part of an upgrade to an xcode program I had running under MacOS 10.5</p>
  
  <p>When I build, I get the error message:</p>
  
  <blockquote>
    <p>Conflicting types for 'uint64'</p>
  </blockquote>
  
  <p>The line that is flagged is located in tiff.h and reads:</p>
  
  <pre><code>typedef TIFF_UINT64_T  uint64;
  </code></pre>
  
  <p>The only other line I can find in the project with TIFF_UINT64_T is located in tiffconf.h and reads:</p>
  
  <pre><code>/* Unsigned 64-bit type */
  #define TIFF_UINT64_T unsigned long
  </code></pre>
  
  <p>In any case, the error makes no sense to me.  There are a large number of similar definitions, none of which flag the same error.  Is it possible that the library libtiff.la has a conflicting definition?  Is there any way to check this?  I cannot get NM or otool to reveal what is in the library.</p>
  
  <p>Other than that, I am at a loss on where to look.  I have done the configure/make/install several times in case it is some omission in the process, but to no avail.</p>
