e03983a32c Let cmp(1) grow in -x option to print differences in contemporarry hex
format rather than the mixed decimal/octal format of -l.

96846ff646 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

8abdc2eb40 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.

c28065c606 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.

2ae09ad871 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.
