Simplify a bit and constify as well. Since the file is mapped read-only,
use const references to access its data.

cast to size_t

- sprinkle CONSTCOND
- back to char * to simplify code, requested by gimpy

don't do arithmetic on void pointer.

fix lint.

Introduce a new accessor macro N_NAME() to access the n_name field
in struct nlist, since it's accessed differently depending on
whether we do a.out or not. Use this macro as appropriate in the
nlis

Introduce a new accessor macro N_NAME() to access the n_name field
in struct nlist, since it's accessed differently depending on
whether we do a.out or not. Use this macro as appropriate in the
nlist* functions.
Also replace some includes of <a.out.h> with <nlist.h>, to fix build
problem for mips.

A variation on the sign-compare fix for these.

fix -Wsign-compare issue (on alpha)

Avoid "unsigned < 0" comparison by open-coding the remaining part
of the check() macro.

netbsd.org->NetBSD.org

sweep of my licenses (userland files w/o only my copyright) for
consistency. (no functional changes)

fix up NetBSD RCS Ids to match the standard, and the leading comment as
to match as well. No functional changes.

Remove a bit of lint.

back out the #ifdef _DIAGNOSTIC argument checks; too many people complained.
_DIAGASSERT() is still retained.

* use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),

* use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.

the first two items result in the addition of code similar to the
following in various functions:

_DIAGASSERT(path != NULL)
#ifdef _DIAGNOSTIC
if (path == NULL) {
errno = EFAULT;
return (-1);
}
#endif

MAP_COPY -> MAP_PRIVATE

Need "namespace.h".

remove obsolete register declarations

use MAP_COPY|MAP_FILE.

Fix RCSID's

clone from nlist_elf32.c (with ECOFF mods). Adds comments,
optimization, cleanup.

kill recently added 'check' functions, since they only add code to be more
expensive, i.e. they save nothing and add code.

Seriously revamp libc's nlist()/__fdnlist() support:
(1) split nlist() into multiple files, for clarity and to make
ELF 32/64 support easier,
(2) support multiple executable types at the same

Seriously revamp libc's nlist()/__fdnlist() support:
(1) split nlist() into multiple files, for clarity and to make
ELF 32/64 support easier,
(2) support multiple executable types at the same time, and
(3) add support for 32- and 64-bit ELF (32-bit ELF support
originally from OpenBSD, but with several bug fixes so
that it actually handles symbols types more correctly
(and therefore _works_ for some of the more tricky uses
of the nlist routines) and changes for 64-bit ELF support).
