own CVS tree will help minimize CVS conflicts.  Maybe not.
Blame Graff for getting me to trim all trailing whitespace.

last idenfier, and IRIX whined about it.  Repeatedly.  Sigh.

                        dns_rcode_*, dns_opcode_*, and dns_trust_* are
                        also now cast to their appropriate types.

                        cast to dns_rdatatype_t via macros of their same name
                        so that they are of the proper integral type wherever
                        a dns_rdatatype_t is needed.

(And a few prototypes that I recently bogusly changed to take "int" parameters
in place of "dns_rdatatype_t" to accomodate the type of an enum identifier
have been reverted to again properly take a dns_rdatatype_t.)

Mostly, several functions that take pointers as arguments, almost
always char * pointers, had those pointers qualified with "const".
Those that returned pointers to previously const-qualified arguments
had their return values qualified as const.  Some structure members
were qualified as const to retain that attribute from the variables
from which they were assigned.

The macro DE_CONST is used to deal with a handful of very special
places where something is qualified as const but really needs to have
its const qualifier removed.

rdata.c now defines macros for the prototypes of the basic rdata functions,
and all of the lib/dns/rdata/**/*.c files now use them.

Some minor integer-compatibility issues.  (IE, ~0x03 is a signed int,
so assigning it to an unsigned int should use a cast.  The type of an
enum member is int, so there are some conversion issues there, too.)

A pointers-to-function should not be cast to a pointer-to-object.

Variables should not be named for C reserved identifiers.

One or two set-but-not-used variables removed.

Minor other ISC style cleanups.

Cleanup of redundant/useless header file inclusion.

ISC style lint, primarily for function declarations and standalone
comments -- ie, those that appear on a line without any code, which
should be written as follows:
   /*
    * This is a comment.
    */

Be far, far noisier about 'generated file; do not edit' to keep the important message from disappearing between copyright notices (say, in rdatastruct.h)

Add types that don't have an associated file (type 0, type 'uid', etc) to the array, rather than special-casing them when printing.  This lets us sort on things easier.

build a table of them using gen.c.  This means the names are stored twice,
but that will change in the near future.  This will speed up number to text
conversions for rdatatypes, and I plan on speeding up text->number as
well, soon.

  platform-specific handling of option parsing and directory iteration.

gen.c:
  use gen-unix.h/gen-win32.h

use isc_dir_* and isc_commandline_parse.

	it will need to be freed, dns_rdata_freestruct().
	Changes to implement this.

	Added C++ support to rdatastruct.h
