+ * libio/bits/types/__fpos_t.h, libio/bits/types/__fpos64_t.h:
+ New single-type headers split from _G_config.h.
+ * libio/bits/types/cookie_io_functions_t.h
+ * libio/bits/types/struct_FILE.h
+ New single-type headers split from libio.h.
+
+ * libio/Makefile: Install the above new headers. Don't install
+ libio.h, _G_config.h, bits/libio.h, bits/_G_config.h, or
+ bits/libio-ldbl.h.
+ * libio/_G_config.h, libio/libio.h: Delete file.
+
+ * libio/bits/libio.h: Remove improper-inclusion guard.
+ Include stdio.h and don't repeat anything that it does.
+ Define _IO_fpos_t as __fpos_t, _IO_fpos64_t as __fpos64_t,
+ _IO_BUFSIZ as BUFSIZ, _IO_va_list as __gnuc_va_list,
+ __io_read_fn as cookie_read_function_t,
+ __io_write_fn as cookie_write_function_t,
+ __io_seek_fn as cookie_seek_function_t,
+ __io_close_fn as cookie_close_function_t,
+ and _IO_cookie_io_functions_t as cookie_io_functions_t.
+ Define _STDIO_USES_IOSTREAM, __HAVE_COLUMN, and _IO_file_flags
+ here, in the "compatibility defines" section. Remove an #if 0
+ block. Use the "body" macros from bits/types/struct_FILE.h to
+ define _IO_getc_unlocked, _IO_putc_unlocked, _IO_feof_unlocked,
+ and _IO_ferror_unlocked.
+ Move prototypes of __uflow and __overflow...
+
+ * libio/stdio.h: ...here. Don't include bits/libio.h.
+ Don't define _STDIO_USES_IOSTREAM. Get __gnuc_va_list
+ directly from stdarg.h. Include bits/types/__fpos_t.h,
+ bits/types/__fpos64_t.h, bits/types/struct_FILE.h,
+ and, when __USE_GNU, bits/types/cookie_io_functions_t.h.
+ Use __gnuc_va_list, not _G_va_list; __fpos_t, not _G_fpos_t;
+ __fpos64_t, not _G_fpos64_t; FILE, not struct _IO_FILE;
+ cookie_io_functions_t, not _IO_cookie_io_functions_t;
+ __ssize_t, not _IO_ssize_t. Unconditionally define
+ BUFSIZ as 8192 and EOF as (-1).
+
+ * libio/bits/stdio.h: Add multiple-include guard. Use the "body"
+ macros from bits/types/struct_FILE.h instead of _IO_* macros
+ from libio.h; use __gnuc_va_list instead of va_list and __ssize_t
+ instead of _IO_ssize_t.
+ * libio/bits/stdio2.h: Similarly.
+
+ * libio/iolibio.h: Add multiple-include guard.
+ Include bits/libio.h after stdio.h.
+ * libio/libioP.h: Add multiple-include guard.
+ Include stdio.h and bits/libio.h before iolibio.h.
+
+ * include/bits/types/__fpos_t.h, include/bits/types/__fpos64_t.h
+ * include/bits/types/cookie_io_functions_t.h
+ * include/bits/types/struct_FILE.h: New wrappers.
+
+ * bits/_G_config.h, sysdeps/unix/sysv/linux/_G_config.h:
+ Get definitions of _G_fpos_t and _G_fpos64_t from
+ bits/types/__fpos_t.h and bits/types/__fpos64_t.h
+ respectively. Remove improper-inclusion guards.
+
+ * conform/data/stdio.h-data: Update expectations of va_list.
+ * scripts/check-installed-headers.sh: Remove special case for
+ libio.h and _G_config.h.
+
+

[BZ #15105]
Deprecated and removed features, and other changes affecting compatibility:
+ * The nonstandard header files <libio.h> and <_G_config.h> are no longer
+ installed. Software that was using either header should be updated to
+ use standard <stdio.h> interfaces instead.
+
* The stdio.h functions 'getc' and 'putc' are no longer defined as macros.
This was never required by the C standard, and the macros just expanded
to call alternative names for the same functions. If you hoped getc and
