	* aclocal.m4: Regenerate.
	* configure.in (GLIBCPP_ENABLE_C99): Use it, on by default.
	* configure: Regenerate.
	* configure.in (GLIBCPP_ENABLE_LONG_LONG): Set default to yes.
	* configure: Regenerate.
	* include/c_std/bits/std_cwchar.h: Put wcstold, wcstoll, wcstoull
	into c99.
	* include/c_std/bits/std_cmath.h: Bring C99 functions into c99
	namespace.
	* include/c_std/bits/std_cstdlib.h: Same.
	* docs/html/configopts.html: Update.
	* testsuite/26_numerics/c99_macros.cc: Edit, use cmath instead of
	math.h
	(test_c99_classify): Add.
	* config/os/gnu-linux/bits/os_defines.h (_GNU_SOURCE): Remove.
	(_ISOC99_SOURCE): Remove.

	* include/bits/stl_algo.h: Use _GLIBCPP_HAVE_DRAND48.
	* include/bits/c++config (__STL_ASSERTIONS): Simplify.
	* acinclude.m4 (GLIBCPP_CHECK_STDLIB_SUPPORT): Add check for drand48.

<DD><P>The &quot;long long&quot; type was introduced in C99, along
with bunches of other functions for wide characters, and math
classification macros, etc. If enabled, all C99 functions not
specified by the C++ standard will be put into namespace c99,
and then all names in the c99 namespace will be injected into
namespace std, so that C99 functions can be used "as if" they
were in the C++ standard (as they will eventually be in some
future revision of the standard, without a doubt.) By default,
C99 support is on, assuming the configure probes find all the
necessary functions and bits necessary.

support for &quot;long long&quot; into the library
