Benjamin Kosnik 0517cb9903 [multiple changes]
2000-10-02  Steven King  <sxking@uswest.net>

        * mkcshadow: Fixed script to output proper include guard.
        * bits/char_traits.h: Cleaned up types in char_traits<char> functions.
        * libio/_G_config.h: Hacked to make work with shadow heraders.
        * shadow/*: Hacked to make shadow headers work.

2000-10-02  Benjamin Kosnik  <bkoz@purist.soma.redhat.com>

	Self-compile with shadow headers.
	* acconfig.h (_GLIBCPP_USE_SHADOW_HEADERS): Define. Eventually,
	like _GLIBCPP_USE_NAMESPACES before it, this macro will die when
	it becomes the default way the library is built.
	* acinclude.m4 (GLIBCPP_ENABLE_SHADOW): New macro.
	* config/gnu-linux/bits/ctype_base.h (ctype_base): Use it.
	* config/gnu-linux/ctype.cc (ctype): Use it.

	* src/localename.cc (locale::_Impl::_M_replace_categories): Remove
	call to assert.
	* src/locale.cc: Explicitly cast mbstate_t to void* in calls to
	memset. This should not be necessary, but an ambiguous overload
	with it in.

	* shadow/bits/std_cwchar.h: Fix.
	* shadow/wchar.h: Fix.

	* config/gnu-linux/bits/ctype_base.h (ctype_base): Inject ctype
	enums into namespace std:: for ctype_base enum. Other OS types
	will have to do this as well.
	* config/gnu-linux/ctype.cc (ctype): Inject ctype data into
	namespace std, in particular __ctype_toupper, __ctype_tolower,
	__ctype_b.

	* shadow/iolibio.h: New file.
	* shadow/bits/wrap_iolibio.h: New file.
	* shadow/libioP.h: New file.
	* shadow/bits/wrap_libioP.h: New file.
	* shadow/bits/wrap_fcntl.h: New file.
	* shadow/fcntl.h: New file.
	* shadow/iconv.h: New file. Inject iconv names into the global
	namespace, unmangled for the moment.
	* shadow/bits/wrap_iconv.h: New file.
	* shadow/unistd.h: Remove. Useless.
	* shadow/bits/wrap_unistd.h: Remove.

	* src/Makefile.am: Take out machine-ansi.h, add fcntl.h unistd.h.
	* src/Makefile.in: Regenerate.

	* config/c_io_libio.h (_IO_codecvt): Change to normal C++ decl.

	* shadow/libio.h: Fix.
	* shadow/bits/wrap_libio.h: Fix.

	* shadow/bits/std_clocale.h: Remove typedef struct construct,
	which will not compile.
	* shadow/bits/std_ctime.h: Same.

	* shadow/pthread.h: New file. Put pthreads types and functions
	into global scope, which is probably not the correct long-term
	solution but has to be done at the moment before libio wrappers
	can even be started.
	* shadow/bits/wrap_pthread.h: New file.

	* bits/std_ios.h: Formatting tweak.
	* shadow/bits/std_cstdio.h: Format. Remove extraneous bits.

	* acinclude.m4 (GLIBCPP_CHECK_COMPILER_FEATURES): Add -Werror to
	tests for compiler features.
	* aclocal.m4: Regenerate.
	* configure: Regenerate.

	* config/c_io_libio.cc: Remove fcntl.h include, as SEEK_SET
	redefined.
	* libio/libioP.h: Comment out fcntl.h include.

	* shadow/math.h: Add in float and long declarations, as per ISO C9X.

	* bits/c++config: Define _ISOC99_SOURCE.

	* acinclude.m4 (GLIBCPP_ENABLE_SHADOW): Add -fno-builtins to
	CSHADOWFLAGS, as well as _ISOC99_SOURCE.
	* aclocal.m4: Regenerate.
	* configure: Regenerate.
	* src/Makefile.am (CSHADOW_INCLUDES): Enable, again.
	(CSHADOW_INCLUDES): Add -I$(top_srcdir)/std before shadow include dir.
	(CXXCOMPILE): Remove $(DEFS), which searches $(top_srcdir) before
	std or shadow directories.
	(LTCXXCOMPILE): Same.
	(INCLUDES): Add $(top_builddir) before $(top_srcdir).
	(AC_CXXFLAGS): Add CSHADOWFLAGS.
	* src/Makefile.in: Regenerate.

	* src/complex.cc (FCT): Change ::name to name.
	* src/complexl.cc (FCT): Same. Use _GLIBCPP_USE_LONG_LONG here.
	* src/complexf.cc (FCT): Same.

	* src/complexf.cc: Remove FCT define, as things are properly
	overloaded in the std namespace with the shadow headers.
	* src/complexl.cc: Same.
	* src/complex.cc: Same.
