+ that the argument is a size, which might not fit in 'int' anyway,

+ 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.

+ socklen: do not depend on sys_socket
+ While trying to modify Emacs to use gnulib's socklen module,
+ I discovered a circular dependency: socklen depends on sys_socket
+ and vice versa. Emacs can use socklen, but it does not need
+ sys_socket because it has its own substitute for sys/socket.h.
