is now exit(DIFF_EXIT).

6d9d3152cc Let cmp(1) grow in -x option to print differences in contemporarry hex
format rather than the mixed decimal/octal format of -l.

b8d073ef7a More egcs warning fixes:
o main returns int not void
	o use return 0 at end of main when needed
	o use braces to avoid potentially ambiguous else
	o don't default to type int
	o #ifdef 0 -> #if 0

ee019a53dc Sweep through the tree fixing mmap() usage:
- Use MAP_FAILED instead of the constant -1 to indicate
    failure (required by POSIX).
  - Removed flag arguments of '0' (required by POSIX).
  - Fixed code which expected an error return of 0.
  - Fixed code which thought any address with the high bit set
    was an error.
  - Check for failure where no checks were present.

9c0cd3f9df Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

905959b15e Our mmap(2) has a limitation where the `offset' parameter must be
page-aligned.  cmp(1) should know about this flaw, and work around it.

While i was at it, fixed an uninitialized variable as reported by
-Wall.

804439a665 When mmap is used, do an madvise(MADV_SEQUENTIAL) to make things
go much more quickly when file input is really done.  Of course, the
fully cached case will make no difference.

6d2b5649a0 I don't like what they did to cmp(1) in 4.4 Lite; now it whines all
the time, even with -s.  Make cmp SHUT UP about non-existant files
when run with -s.
