3.3 problem: <ctype.h> and <iostream>

[Craig Rodrigues <rodrigc at attbi dot com>]

Hi,

I just did a contrib/gcc_update in my CVS tree on the 3.3 branch
and am now encountering a new problem.

If I have the following file:

#include <ctype.h>
#include <iostream>
#include <ios>

int main(int argc, char *argv[])
{
}


Compiling it yields the following error on RedHat Linux 7.2 system:

If I change the order of the  includes to:

#include <iostream>
#include <ios>
#include <ctype.h>

Then the error goes away.

What's going on here?
