-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.
