	* include/c/bits/std_cmath.h: Fix double declarations in namespace std.

	Clean up naming, consistency in "C" library autoconf testing.
	* acinclude.m4 (GLIBCPP_CHECK_CTYPE): For consistency, change to
	GLIBCPP_CHECK_CTYPE_SUPPORT.
	(GLIBCPP_CHECK_STDLIB_SUPPORT): Add.
	* aclocal.m4: Regenerate.
	* configure.in: And here.
	Add call to GLIBCPP_CHECK_STDLIB_SUPPORT.
	* configure: Regenerate.

* acinclude.m4 (GLIBCPP_CHECK_LINKER_FEATURES): Comment out
--gc-sections stuff entirely to avoid misleading people.
(GLIBCPP_ENABLE_CSTDIO): Merge need_libio and need_xtra_libio.
* libio/Makefile.am (LIBIO_SRCS,LIBIO_WSRCS,LIBIO_XTRA_SRCS):
Rearrange and merge.
* libio/libio.h: Simplify, make fewer assumptions. Define those
macros which must be defined.
* config/os/solaris/solaris2.7/bits/os_defines.h: Simplify as a
result.
