Re: [Libguestfs] [PATCH 2/2] Cast return value of be64toh to uint64_t before printing.

With glibc 2.16-24.fc18, be64toh is a macro around __bswap_64 which is
defined as:

   unsigned long long int __bswap_64 (unsigned long long int __bsx);

Unfortunately on 64 bit platforms, unsigned long long int cannot be
printed using the expansion of PRIu64 ("%lu") resulting in about a
dozen errors such as:

   ldm.c:1129:5: error: format '%lu' expects argument of type 'long unsigned int', but argument 11 has type 'long long unsigned int' [-Werror=format]

This commit corrects the problem by casting the result to uint64_t,
although I'm fairly sure that this is really a bug in glibc.

I already have this patch locally, but it seems I forgot to push it. Sorry! It's pushed now.
