Test source to produce the error

Description of problem:
I found that cups-pdf was failing to write pdf files to the users home directories that were housed in a gluster volume. After added some proper error checking to the source, I discovered that it was failing with EOVERFLOW. This affects nearly all EL5 packages.

I was able to work around it by defining "-D _FILE_OFFSET_BITS=64" in rebuilding that one file I needed.

This can be tested by compiling the attached:
  gcc -g -O0 -o stat stat.c

Copy that to a gluster volume mounted on 32 bit EL5 and run it. It will return:
  stat: Value too large for defined data type
  stating stat: -1 00000000a006a2b9

Note the 32bit truncation of the inode.

Compiling with:
  gcc -D _FILE_OFFSET_BITS=64 -g -O0 -o stat stat.c

and performing the same test produces
  stating stat: 0 00000000a006a2b9

Notice it's still a truncated inode (actual inode was 9bd28da4a006a2b9).

Since EL5 cannot be rebuilt with _FILE_OFFSET_BITS=64, there should be a solution in the fuse interface.
