ChangeLog, gen_uuid.c:

ChangeLog, gen_uuid.c:
  gen_uuid.c (get_random_bytes): Make more paranoid about misbehaving
  	/dev/urandom.  If we get a return of zero without an error more than 8
  	times in a row, we break out and return an error.  Also, if
  	/dev/urandom doesn't exist, try /dev/random.
ChangeLog, ext2fs.h:
  ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine how
  	to define __s64 and __u64.  Turn off "compression is experimental"
  	warning if the cpp macro I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is
  	defined.
