(lc_message_charset): Ditto.
(loadlocale): Set charset of the "C" locale to "UTF-8" on Cygwin.
* libc/stdlib/mbtowc_r.c (__mbtowc): Default to __utf8_mbtowc on
Cygwin.
* libc/stdlib/wctomb_r.c (__wctomb): Default to __utf8_wctomb on
Cygwin.
* libc/stdlib/sb_charsets.c (__micro_atoi): Allow five-digit codepage
numbers.
* libc/locale/locale.c (loadlocale): Set MB_CUR_MAX to 1 for KOI8
charsets.
* libc/stdlib/local.h (__cp_conv): Remove incorrect number of codepages.
* libc/locale/locale.c: Update documentation.
(loadlocale): Map "KOI8-R" and "KOI8-U" to CP20866 and CP21866.

* libc/stdlib/sb_charsets.c (__cp_conv): Add KOI8-R (Russian, CP20866)
and KOI8-U (Ukrainian, CP21866) to Windows codepage conversion tables.
* libc/ctype/ctype_cp.h (__ctype_cp): Likewise for ctype tables.
* libc/posix/popen.c (popen): Fix documented prototype.
Improve popen compatibility with glibc.
* libc/posix/popen.c (popen): The 2006-08-22 change to use
FD_CLOEXEC disagrees with other implementations; instead, use
pidlist to work even when fcntl is not available. Meanwhile,
support the 'e' modifier to set CLOEXEC, as in glibc. Drop
cygwin-specific code, now that cygwin has its own version.
* libc/posix/Makefile.am (CHEWOUT_FILES): Document popen.
* libc/posix/posix.tex: New file.

* libc/posix/Makefile.am (CHEWOUT_FILES): Document popen.
* libc/posix/posix.tex: New file.
pair handling to be more bullet-proof even with incomplete UTF-8
sequences. Add check for 4 byte sequences resulting in values
outside the valid Unicode range. Add a comment to clarify checking
for invalid CESU-8 sequences.
radix char instead of assuming length 1.
* libc/stdlib/gdtoa-gethex.c: Remove use of USE_LOCALE.
(gethex): Allow multibyte decimal point.
Fix compiler warnings due to different signedness of pointer types.
* libc/stdlib/strtod.c: Remove use of USE_LOCALE.
(_strtod_r): Allow multibyte decimal point.
* libc/stdlib/wcstod.c (_wcstod_r): Evaluate correct wide char
endptr position if the decimal point is a multibyte char.
* libc/include/math.h: Simplify fpclassify, isinf, isnan, and signbit
macros to remove un-necessary extension use. isinf and isnan also
changed to use fpclassify. isfinite macro modified to run faster by
only calling fpclassify once instead of possibly twice.
* libc/locale/locale.c (lc_ctype_cjk_lang): New static int.
(loadlocale): In case of setting LC_CTYPE, set lc_ctype_cjk_lang
to 1 if the language is "jp", "ko", or "zh", to 0 otherwise.
(__locale_cjk_lang): New function.
* libc/string/local.h (__locale_cjk_lang): Declare.
* libc/string/wcwidth.c: Fix comments.
(__wcwidth): Handle CJK Ambiguous Width characters according
to setting returned by __locale_cjk_lang.
(__jp2uc): Change the scope to static function.
* libc/ctype/local.h (_jp2uc): Define as macro if defined __CYGWIN__.
* libc/string/local.h (_jp2uc): Include ../ctype/local.h.
* configure.in: Add configuration test for long double type existing
and set flag _HAVE_LONG_DOUBLE if true. Fix INIT_ARRAY (.init_array)
and _LDBL_EQ_DBL tests to not link so that will work with
cross-compilers.
* configure: Regenerated.
* Makefile.in: Ditto.
* newlib.hin: Add _HAVE_LONG_DOUBLE flag.
* libc/include/math.h: Change non-builtin defines for HUGE_VAL,
HUGE_VALF, and HUGE_VALL to be constant expressions. Add definitions
for the non-builtin case for INFINITY and NAN. Gate HUGE_VALL and
union __ldmath definitions with (new) _HAVE_LONG_DOUBLE.
*libm/common/s_infconst.c: Change definitions to use values from
float.h instead of non-so-portable integer forms. Mark as being
deprecated (because now removed from math.h, are not used anywhere
in Newlib, itself).
* libc/string/wcswidth.c (wcswidth): Convert japanese wide
characters to Unicode here. Handle surrogate pairs for UTF-16
systems. Call __wcwidth rather than wcwidth.
* libc/string/wcwidth.c: New implementation using Markus Kuhn's
wcwidth implementation for Unicode.
(bisearch): New static function.
(__wcwidth): New function. Take wint_t rather than wchar_t as
parameter to allow full Unicode handling on UTF-16 systems.
Move old wcwidth implementation here for non-multibyte aware
systems.
(wcwidth): Convert japanese wide characters to Unicode here.
Call __wcwidth rather than using iswprint/iswcntrl.
* libc/include/ctype.h (toupper, tolower)
[_MB_EXTENDED_CHARSETS_ISO]: Allow gcc warning when called with
'char' even when we must call the function for correct behavior.
[!_MB_EXTENDED_CHARSETS_ISO]: Fix regression in result type.
* libc/stdio/fgetc.c: Make sure sfp lock is acquired before the
file lock and released before the file lock to avoid a deadlock
scenario.
* libc/stdio/fgets.c: Ditto.
* libc/stdio/fgetwc.c: Ditto.
* libc/stdio/fgetws.c: Ditto.
* libc/stdio/fread.c: Ditto.
* libc/stdio/fseek.c: Ditto.

* libc/stdio/getdelim.c: Ditto.
* libc/stdio/gets.c: Ditto.
