Subject: [PATCH] eliminate protected-visibility data in libc.so with vis.h
preinclude
some newer binutils versions print scary warnings about protected data
because most gcc versions fail to produce the right address
references/relocations for such data that might be subject to copy
relocations. originally vis.h explicitly assigned default visibility
to all public data symbols to avoid this issue, but commit
b8dda24fe1caa901a99580f7a52defb95aedb67c removed this treatment for
stdin/out/err to work around a gcc 3.x bug, and since they don't
actually need it (because taking their addresses is not valid C).
instead, a check for the gcc 3.x bug is added to the configure check
for vis.h preinclude support; this feature will simply be disabled
when using a buggy version of gcc.

From 7b9f57f207b51132f188f750161953b7baf32154 Mon Sep 17 00:00:00 2001
From: Rich Felker <dalias@aerifal.cx>
Date: Thu, 8 Oct 2015 22:03:53 +0000
Subject: fix open_[w]memstream behavior when no writes take place
the specification for these functions requires that the buffer/size
exposed to the caller be valid after any successful call to fflush or
fclose on the stream. the implementation's approach is to update them
only at flush time, but that misses the case where fflush or fclose is
called without any writes having taken place, in which case the write
flushing callback will not be called.
to fix both the observable bug and the desired invariant, setup empty
buffers at open time and fail the open operation if no memory is
available.
