[Bug c++/31459] New: No #pragma GCC visibility {push/pop} (default) in <stdexcept> and <string>

["rjarrett at mathworks dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Generic header defect observed on both x86 and x86_64

Missing  "#pragma GCC visibility push(default)" and "#pragma GCC visibility
pop" directives wrapped around the versions of <stdexcept> and <string> that
ship with GCC 4.0 - 4.2.  See for example <new> or <exception>, which are
properly encased.

Add #pragma GCC visibility push(default) and 
#pragma GCC visibility pop(default) to string and stdexcept

>From new
...
#pragma GCC visibility push(default)

extern "C++" {
...
} // extern "C++"

#pragma GCC visibility pop
....


Workaround:
create a include directory with files 'string' and 'stdexcept' and alter your
include path to ssearch this directory first.

string:

#pragma GCC system_header
#pragma GCC visibility push(default)
#include_next <string>
#pragma GCC visibility pop
