* 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.
