I often have that concern and often it's true :-).
In the case of Fusion. I need the library to create matrices which work with
types other than double.

OK. The first question is... why? I think I can answer that for myself, but
what is in it for the broader audience?

For myself an important issue is that I am, due to inertia, compiler bound. I
love VC7.1. I love the IDE. (IIRC you call this ' screen scraping', but that's
your problem). So that is a hurdle that ConceptGCC has to face for someone like
me. I have my "comp.bat" file set up for checking that stuff compiles with gcc,
but for effortless coding, I head straight for VC7.1. IOW your compiler/IDE has
a great deal of power over what you do

And , maybe ConceptGCC has a similar 'problem'(It's not really a problem) to
the one I have with Quan, but probably more severe, in that most people are
bound to old C style libraries, which frankly don't have a hope of compiling
with ConceptGCC, due to the average *useful* 'Hack' optimisation's that have
been applied. It's simply inertia again.

I think what C++ needs most of all, is a standard GUI, because with that, it
would be easy to plug ConceptGCC, the compiler, into a standard IDE. And with a
standard IDE, it would be quite easy to apply a couple of switches to switch

So, of all the libraries that C++ should have, I think that a standard GUI is
the most important, because it would be so much easier to try out and
demonstrate major changes to C++.

Simply put, ConceptGCC needs a nice UI to show it off, and its a bit sad that
C++ has no way to provide that.

I guess that is the root of the problem.

( And I am currently concerned with trying to make some inroads into that
