difference between eucJP and CP 20932 affecting JIS-X-0212 characters.
Explain.

sequences. Fix a bug in '\0' handling. Reset state->__count on
successful return from non-zero state.

(__set_charset_from_codepage): Handle codepage 20932 as eucJP.
ctype_cp.h out of ALLOW_NEGATIVE_CTYPE_INDEX case.
(__ctype_ptr__): Constify in !_MB_CAPABLE case. Otherwise,
de-constify in !ALLOW_NEGATIVE_CTYPE_INDEX case, too. Add comment.

of ALLOW_NEGATIVE_CTYPE_INDEX.
* libc/include/ctype.h (__ctype_ptr__): Constify in !_MB_CAPABLE case.
(fixup_shms_after_fork): Fix comment. Use NtMapViewOfSection rather
than MapViewOfFileEx to recreate shared memory regions. Add function
name to api_fatal output.

top-down.
pointer-based newlib implementation.
(_ctype_b): Declare.
(__ctype_cp): Move to newlib. Declare.

* include/cygwin/config.h (__EXPORT): Define alongside __IMPORT.
* include/cygwin/version.h (CYGWIN_VERSION_CHECK_FOR_OLD_CTYPE):
Define check for old vs. new ctype implementation.
Bump API minor number.
source files. Add a dependency rule for ctype_o to note
changes in ctype_iso.h and ctype_cp.h.
* libc/ctype/Makefile.in: Regenerate.
* libc/ctype/_tolower.c: Remove file.
* libc/ctype/_toupper.c: Remove file.
