On 32 bits platforms, off_t is a 32 bits signed integer, so we have to test
against a slightly smaller value to make sure it's always valid, otherwise, the
test will always be true on these platforms. I'm assuming 9999999999 was an
arbitrarily large number anyway.

         stream->writeBigDecAsText(fCatalog[i].fFileOffset, 10);
         stream->writeText(" 00000 n \n");
     }
