using namespace std;

template <class Type>
class myclass1
{
  public:
    void test()
    { 
      fd_set myfs;
      FD_ZERO(&myfs);
    }
};

struct dum {};

int main()
{
  myclass1<dum> temp;
  temp.test();
}
>How-To-Repeat:
Compile code above. Note this works fine with g++ 3.0 and higher, but not with 2.95.4. I got this error message:

g++    -c -o main.o main.cc
main.cc: In method `void myclass1<dum>::test()':
main.cc:20:   instantiated from here
main.cc:11: `volatile' undeclared (first use this function)
main.cc:11: (Each undeclared identifier is reported only once
main.cc:11: for each function it appears in.)
main.cc:11: warning:  qualifier ignored on asm
make: *** [main.o] Error 1
