> The signature of strerror_r is not quite detected correctly in libhdfs3.  The code assumes
that {{int foo = strerror_r}} will fail to compile with the GNU type signature, but this is
not the case (C\+\+ will coerce the char* to an int in this case).  Instead, we should do
what the libhdfs {{terror}} (threaded error) function does here.
