Simple string test program

[Tabakovic Arnes <arnes dot tabakovic at sbi dot ch>]

Hi,
I am using the latest version of libstd++ and SGI stl to compile a small
program using gcc compiler. This program is shown below:

#if defined (__GNUG__) && defined (__sun__) 
#define __SINST__ 
#endif 

#include <fstream.h>

// c++ STL Headers
#include "../stl/string"

using namespace std;


int main(int argc, char **argv)
{
	string s1 = "s1";
	string s2 = "s2";

	if (s1 != s2)
		cout << "s1 not equal to s2!" << endl;
	else
		cout << "s1 is equal to s2!" << endl;

	return 0;
}


I get the following error by compiling it with g++:

g++ -c -I../stl testString.cpp -o testString.o
In file included from ../stl/string:17,
                 from testString.cpp:8:

../stl/stl_string_fwd.h:30: parse error before `&' token
../stl/stl_string_fwd.h:30: confused by earlier errors, bailing out
make: *** [testString.o] Error 1


Can anybody help please? By advance, I thank you!
