Problems compiling STLPORT 4.5.3 with g++ 3.3

[Gary]

I am trying to compile the STLPORT 4.5.3 using g++ 3.3 compiler on sun. I
have modified the stl_gcc.h file to point to the correct include path for
the compiler.
I am getting the following errors:

I am not sure how to get fix these errors. I have tried setting the
following defines in the stl_gcc.h file:
//# define _STLP_USE_NEW_IOSTREAMS
//# define _STLP_OWN_IOSTREAMS
//# define _STLP_USE_NO_IOSTREAMS

Setting any one of these flags leads to loads of errors in the
stlport/stl/_string.h file.

I am new to STL and I am trying to port some code to use the g++ compiler
on Sun. I have to use STLPORT 4.5.3 and g++ 3.3. Any help of how to get
around these errors would be greatly appreciated. This code was originally
built on AIX with the IBM C++ compiler and STLPORT 4.5.3.

You include the header iostream.h in one of your files which
officially doesnt exist any more. Probably the errors you
get are caused by this header too.

Simply change the #include to:

#include <iostream> // No .h
using namespace std;

The functions are now in the namespace std, so you have to
add the second line too. Its not the very best policy(its
the lazy way of doing it) to make the whole namespace
available and I recommend that you make the functions you
need individually known.

hope this helps,
