[Bug c++/15773] New: Error, if compiled with -O3 (gettext method name)

["herbert at linuxhacker dot at" <gcc-bugzilla at gcc dot gnu dot org>]

#include <string>
#include <iostream>

class foo
{
   std::string s;
   public:
     foo (const char *a) : s(a) {}

     std::string gettext (void) { return s; }
};

int main (int argc, char **argv)
{
   foo f("test");
   std::string a;

   a=f.gettext();

   std::cout << "Test: " << a << std::endl;

   return 0;
}

Compiled and linked with:
g++ -o t1 t1.cxx
./t1
Test: test

And now with -O3:
g++ -O3 -o t1 t1.cxx
t1.cxx:11: error: parse error before `,' token
t1.cxx:11: error: variable declaration is not allowed here
t1.cxx:11: error: syntax error before `{' token
t1.cxx:12: error: parse error before `}' token
t1.cxx: In function `int main(int, char**)':
t1.cxx:19: error: parse error before `,' token
t1.cxx:19: error: `dcgettext' undeclared (first use this function)
t1.cxx:19: error: (Each undeclared identifier is reported only once for
each
  function it appears in.)
