+ stdio: don't require ignore_value around fwrite
+
+ This patch works around libc bug 11959
+ <http://sources.redhat.com/bugzilla/show_bug.cgi?id=11959>.
+ Without this patch, applications must often write
+ ignore_value (fwrite (...)) even though the ignore_value is
+ not helpful here. It's common to write many objects, using
+ fwrite/printf/etc., and then use ferror to detect output error.
+
+ I considered making this patch optional, but decided against it,
+ because libc is obviously being inconsistent here: there is no
+ reason libc should insist that user code must inspect fwrite
+ return's value without also insisting that it inspect printf's,
+ putchar's, etc. If user code wants to have a strict style where
+ all these functions' values are checked (so that ferror need not
+ be checked), we could add support for that style in a new gnulib
+ module, but in the meantime it's better to be consistent and to
+ support common usage.
+
+ * lib/stdio.in.h (rpl_fwrite): Define this wrapper around fwrite,
+ to work around libc bug 11959, if __USE_FORTIFY_LEVEL indicates
+ that we are compiling in checking mode, and if not C++, and
+ if not already wrapping fwrite for some other reason.
+ (fwrite): #define to rpl_fwrite if the latter is defined.

+ (require_exactly_one_NL_at_EOF_): Renamed from
+ detect_empty_lines_at_EOF_. I opted not to rename the rule,
+ since people may well have .x-sc_... file names tied to the

+ dirname: move m4/dos.m4 functionality into lib/dosname.h
+
+ m4/dos.m4 needs to go. It laboriously invokes the C compiler, and
+ extracts symbols from it, puts them into config.h; but it's much
+ easier to use the symbols directly. filename.h already does this,
+ but it disagrees with dos.m4 in some respects. This patch
+ introduces a different include file dosname.h that packages up
+ dos.m4, and then later we can work on merging filename.h and
+ dosname.h. Applications that need only the easy-to-configure
+ symbols should consider including dosname.h rather than dirname.h.
+ * NEWS: Mention incompatible changes.
+ * m4/dos.m4: Remove.
+ * lib/dosname.h, modules/dosname: New files.
+ * lib/dirname.h (ISSLASH, FILE_SYSTEM_PREFIX_LEN):
+ (FILE_SYSTEM_DRIVE_PREFIX_CAN_BE_RELATIVE):
+ (IS_ABSOLUTE_FILE_NAME, IS_RELATIVE_FILE_NAME): Move to lib/dosname.h.
+ * lib/at-func.c, lib/at-func2.c, lib/openat.c, lib/savewd.c:
+ Include dosname.h, not dirname.h.
+ * lib/rmdir.c, lib/stat.c, lib/unlink.c, lib/unlinkat.c:
+ Include dosname.h, for definitions of symbols like ISSLASH
+ that used to be in config.h.
+ * m4/dirname.m4 (gl_DIRNAME_LGPL): Do not require gl_AC_DOS.
+ * m4/rmdir.m4 (gl_FUNC_RMDIR): Likewise.

+ (critical_factorization): Partially revert changes from

+
+ backupfile: remove unnecessary use of m4/dos.m4
+ * m4/backupfile.m4 (gl_BACKUPFILE): Don't require gl_AC_DOS; none
+ of its symbols are used by the backupfile code. backupfile.c does
+ use a symbol HAVE_DOS_FILE_NAMES, but that symbol is meant only
+ for the rare case of programs that want all their backup file
+ names to live within 8+3 limits, and dos.m4 doesn't address that.
+ * modules/backupfile (Files): Remove m4/dos.m4.
