Hi,

I thought I'd try this out on my WinXP X64 machine.  Creating MEX files 
is working fine but I can't get IPOPT to compile on this machine in the 
usual way, i.e. before adding any flags for the MEX work.  It seems the 
problem is my stdlibc++ on this machine is quite old but I'm not sure 
how to update it, and the recent updates I made should have been quite 
recent.  Perhaps somebody who's built IPOPT on Win64 with the Intel 
compilers can give me a hint about their setup on this platform.

Details:
   1. I get compiler errors for string.clear, here's a tiny example:
#include <iostream>
#include <string>

using namespace std;

int main (int argc, char **argv)
{
   string foo;

   foo = "string foo";

   cout << "tiny example: foo=" << foo << endl;
   foo.clear();
   cout << "after clear: foo=" << foo << endl;
}

$ icl  myclear.cpp
Intel(R) C++ Compiler for Intel(R) EM64T-based applications, Version 9.1 
    Buil
d 20070322

myclear.cpp
myclear.cpp(13): error: class "std::basic_string<char, 
std::char_traits<char>, std::allocator<char>>" has no member "clear"
     foo.clear();
         ^

compilation aborted for myclear.cpp (code 2)

   2. I can hack around the .clear errors but then I get errors about 
string.push_back, so I better just fix the problem.

   3. Here's the cl that's used by icl:
$ cl
Microsoft (R) C/C++ Optimizing Compiler Version 14.00.40310.41 for AMD64

usage: cl [ option... ] filename... [ /link linkoption... ]
