What is the difference between DigitalMars C++ compiler and other ones (for instance, GNU gcc/g++)  ? When is it worth using DigitalMars C++ compiler ?

Generating very fast code, very fast.

Is there DigitalMars C++ compiler for Windows 2000 ?

Yes.

However :


==============================
Windows 2000
dmc - How to know the version?
==============================

====== C++ code : BEGIN ======
// File ttt.cpp
#include <iostream>
using namespace std;

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

====== C++ code : END ========

====== Compilation : BEGIN ======

%dmc ttt.cpp

Fatal error: unable to open input file 'iostream'
--- errorlevel 1

====== Compilation : END ========

Yes, DMC++ works for Windows 2000, too.

To get iostream, you'll need STLport 4.5.3, check www.digitalmars.com/download/freecompiler.html for instructions.

The most (usefully) responsive vendor in the world (or, at least, in my
universe of experience).

For example, for some research I was doing I had a need for the compiler to tell me when a C-style cast (as opposed to C++'s static_cast<>, const_cast<>, dynamic_cast<> & reinterpret_cast<>) was being used. (FYI, there are a few circumstances where the C-style cast is needed, when doing certain template techniques, but there are only a very few.)

I banged off a request to Walter, and it was in within a week! You can't say fairer than that.

The one current complaint with DigitalMars is its relatively old template support. However, in the vane previously described, Walter is rapidly bringing it up to conformance, and I have no doubt that it will be better than some other, more widely known, ones (you know who I'm talking about ...) in the next few months.

The template support is pretty modern now as of 8.29.

that is a nice advertizing sentence !

Sure. I wasn't meaning to say DM is bad, just that there are some aspects that'll still kill it readily

As I mentioned to you in email the other week, I'm about to update the STLSoft libraries and will be focusing, amongst others, on DM, so will be sending you lots of bug reports very soon. :)
