2264536172 Note briefly how to avoid the problem where 0 can be a valid successful 
return as well as an error. Suggested by Robert Elz in follow up to PR 39392.

04cc7786fc rework bulid breakage problem on linux. 
ldef.h: s/1<<8/_CTYPE_CACHE_SIZE/
ctype_local.h: use limits.h instead of machine/limits.h
runetype_local.h: don't use HAVE_NBTOOL_CONFIG as evil way.

64a7d4fa9a 1. hide _CTYPE_PRIVATE section in ctype.h, move them to private header ctype_local.h. 
2. do not use _CTYPE_NUM_CHARS macro to read data from LC_CTYPE(old BSDCTYPE style) database.
   because 1<<CHAR_BIT is MD, so i added MI macro _CTYPE_CACHE_SIZE(1<<8).
3. remove _NB_CACHED_RUNE macro, use _CTYPE_CACHE_SIZE instead.

ce1c570bfe Rewrite much of the page. 
Provide much more detailed and structured discussion. Notably, try to gather
some of the conditions around the famous undefined behavior; these functions
(or the implementations) are quite prone to such behavior.

Add compatibility notes. (The big change here is that in SUSv4 it is no
longer mandated that the directory streams are implemented by using file
descriptors.)

XXX: Please proofread this. Consider also adding some additional notes. For
     instance, I left the semantics about "." and ".." out.  The returned
     errno's should be enumerated as well.

4519228649 Improvements to wording and markup. 
In addition, list more bugs and caveats. Namely, the NetBSD implementation
(like the FreeBSD one where this was ported to) requires that the comparison
keys are allocated dynamically, and that hdestroy() will try to free(3) each
key. This obviously severely limits the portability, given that other
implementations (for example, the Linux one) make no such assumptions. Both
approaches are legitimate, and thus the real bug is in the ambiguity of the
standard.
