Thanks! BTW, here's what changed (esp. re: #17):


Changes from 3.1.8 to 4.0.0
---------------------------

1. The special files /dev/pid, /dev/ppid, /dev/pgrpid and /dev/user
are
   now completely gone. Use PROCINFO instead.

2. The POSIX 2008 behavior for `sub' and `gsub' are now the default.
   THIS CHANGES BEHAVIOR!!!!

3. The \s and \S escape sequences are now recognized in regular
expressions.

4. The split() function accepts an optional fourth argument which is
an array
   to hold the values of the separators.

5. The new -b / --characters-as-bytes option means "hands off my
data"; gawk
   won't try to treat input as a multibyte string.

6. There is a new --sandbox option; see the doc.

7. Indirect function calls are now available.

8. Interval expressions are now part of default regular expressions
for
   GNU Awk syntax.

9. --gen-po is now correctly named --gen-pot.

10. switch / case is now enabled by default. There's no longer a need
    for a configure-time option.

11. Gawk now supports BEGINFILE and ENDFILE. See the doc for details.

12. Directories named on the command line now produce a warning, not
    a fatal error, unless --posix or --traditional.

13. The new FPAT variable allows you to specify a regexp that matches
    the fields, instead of matching the field separator. The new
patsplit()
    function gives the same capability for splitting.

14. All long options now have short options, for use in `#!' scripts.

15. Support for IPv6 is added via the /inet6/... special file. /
inet4/...
    forces IPv4 and /inet chooses the system default (probably IPv4).

16. Added a warning for /[:space:]/ that should be /[[:space:]]/.

17. Merged with John Haque's byte code internals. Adds dgawk debugger
and
    possibly improved performance.

18. `break' and `continue' are no longer valid outside a loop, even
with
    --traditional.

19. POSIX character classes work with --traditional (BWK awk supports
them).

20. Nuked redundant --compat, --copyleft, and --usage long options.

21. Arrays of arrays added. See the doc.

22. Per the GNU Coding Standards, dynamic extensions must now define
    a global symbol indicating that they are GPL-compatible. See
    the documentation and example extensions.
    THIS CHANGES BEHAVIOR!!!!

23. In POSIX mode, string comparisons use strcoll/wcscoll.
    THIS CHANGES BEHAVIOR!!!!

24. The option for raw sockets was removed, since it was never
implemented.

25. Gawk now treats ranges of the form [d-h] as if they were in the C
    locale, no matter what kind of regexp is being used, and even if
    --posix.  The latest POSIX standard allows this, and the
documentation
    has been updated.  Maybe this will stop all the questions about
    [a-z] matching uppercase letters.
    THIS CHANGES BEHAVIOR!!!!

26. PROCINFO["strftime"] now holds the default format for strftime().

27. Updated to latest infrastructure: Autoconf 2.68, Automake 1.11.1,
    Gettext 0.18.1, Bison 2.5.

28. Many code cleanups. Removed code for many old, unsupported
systems:
        - Atari
        - Amiga
        - BeOS
        - Cray
        - MIPS RiscOS
        - MS-DOS with Microsoft Compiler
        - MS-Windows with Microsoft Compiler
        - NeXT
        - SunOS 3.x, Sun 386 (Road Runner)
        - Tandem (non-POSIX)
        - Prestandard VAX C compiler for VAX/VMS
        - Probably others that I've forgotten

29. If PROCINFO["sorted_in"] exists, for(iggy in foo) loops sort the
    indices before looping over them.  The value of this element
    provides control over how the indices are sorted before the loop
    traversal starts. See the manual.

30. A new isarray() function exists to distinguish if an item is an
array
    or not, to make it possible to traverse multidimensional arrays.

31. asort() and asorti() take a third argument specifying how to sort.
    See the doc.
