gettext-0.18.1/gnulib: gettext-tools/tests/lang-c++ fails with gcc2.95

[Christian Weisgerber]

As seen on OpenBSD/sparc, the gettext-tools/tests/lang-c++ check
fails to compile with gcc2.95:

In file included from ../gnulib-lib/sys/select.h:56,
                 from /usr/include/sys/types.h:224,
                 from /usr/include/stdio.h:45,
                 from ../gnulib-lib/stdio.h:35,
                 from prog.cc:13:
../gnulib-lib/string.h:497: syntax error before `('
../gnulib-lib/string.h:587: syntax error before `('
../gnulib-lib/string.h:829: syntax error before `('
FAIL: lang-c++

What happens is that declarations from gnulib-lib/string.in.h like
this one

_GL_FUNCDECL_SYS (rawmemchr, void *, (void const *__s, int __c_in)
                                     __attribute__ ((__pure__))
                                     _GL_ARG_NONNULL ((1)));

after preprocessing end up as

extern "C"    void *   rawmemchr    (void const *__s, int __c_in)
                                     __attribute__ (( ))
                                        ;

because __pure__ is defined away for gcc2.95.  However,
__attribute__(( )) causes an error for C++ (but not for plain C).
