..\..\third_party\cld_2\src\internal\offsetmap.cc(82,43) :  warning(clang): 
format specifies type 'long' but the argument has type 'size_type' (aka 
'unsigned int') [-Wformat]
  fprintf(fout, "Offsetmap: %ld bytes\n", diffs_.size());
                            ~~~           ^~~~~~~~~~~~~
                            %u

There's no great portable way to printf size_t types. Since this is debugging 
code, I suggest this patch:

Nicos-MacBook-Pro:src thakis$ svn diff

   }

   Flush();    // Make sure any pending entry gets printed
-  fprintf(fout, "Offsetmap: %ld bytes\n", diffs_.size());
+  fprintf(fout, "Offsetmap: %lu bytes\n",
+          static_cast<unsigned long>(diffs_.size()));
   for (int i = 0; i < static_cast<int>(diffs_.size()); ++i) {
     fprintf(fout, "%c%02d ", "&=+-"[OpPart(diffs_[i])], LenPart(diffs_[i]));
     if ((i % 20) == 19) {fprintf(fout, "\n");}

Can you land this, please?

Committed as r167. For consistency with the for-loop immediately following, I 
stuck with static_cast<int> and %d. This should fix your error, please confirm!

That was fast, thanks!
