using xlocale to implement std::locale class

[Takeshi Kobayakawa]

I made a patch(attached) to work std::locale using xlocale on darwin 
(MacOSX).

To apply the patch, goto libstdc++ directory and
patch -p1 < (attached filename)

To make the patched code work, one has to configure with 
--enable-clocale=darwin-xlocale.


However in this point, I only checked a trivial test like
locale::global(locale("");
and checked IO thru wcin/wcout to wstring works correctly.
Sorry but I could not catch up with what was discussed in this ML about 
the testsuite of std::locale. What kind of test should I do?


Additionaly, since Jonathan mentioned below, I checked the standards for 
what is used in config/local/gnu.(CX means extension to the ISO C standard.)

nl_langinfo_l POSIX.2008
strcoll_l POSIX.2008(CX)
strftime_l POSIX.2008(CX)
strtod_l
strtof_l
strtold_l
strxfrm_l POSIX.2008(CX)
newlocale POSIX.2008
freelocale POSIX.2008
duplocale POSIX.2008
uselocale POSIX.2008

iswctype_l POSIX.2008(CX)
towlower_l POSIX.2008(CX)
towupper_l POSIX.2008(CX)
wcscoll_l POSIX.2008(CX)
wcsftime_l
wcsxfrm_l POSIX.2008(CX)
wctype_l POSIX.2008(CX)

Maybe, directory arrangement like config/locale/ieee_1003.1-2008{,cx} 
would be better abstraction than what I made in this patch.
