STL includes don't seem to take effect in g++ 3.0.2

[Jeremy Lin <jjlin at OCF dot Berkeley dot EDU>]

I recently built gcc 3.0.2 on solaris 8, and g++ won't compile programs
using the STL (gcc works fine though). For example, this simple program:

#include <iostream>

int main ()
{
    cout << "hello world" << endl;
    return 0;
}

yields:

hello.cc: In function `int main()':
hello.cc:5: `cout' undeclared (first use this function)
hello.cc:5: (Each undeclared identifier is reported only once for each
function it appears in.)
hello.cc:5: `endl' undeclared (first use this function)

Running with -v gives:

So it seems to be searching the proper paths, and in fact, trussing
everything shows that the include files are being read by cc1plus. We have
a g++ 2.95.2 that works fine, also. I'd really appreciate it if anyone
could offer any ideas about how to fix this.

Thanks,
