Linuc/gcc port (nearly done)

[Peter Schmitteckert-2]

Dear Developers,

this morniung I adapted your QuantLib 0.0.1 Source
to compile on my Linux 2.2.17 using
gcc 2.95.2.  I had to tweak a few places only,
not because of limititations of g++, but because of
some inconsistencies of the C++ standard library
(limits & sstream)

The only problem I've encountered ist in "cranknicolson.h":

        template <int constant>
        class CrankNicolsonTimeSetter {};

Here you specify a templated class without using the
template parameter. In my opinion I can't blame g++
for not compiling this, since according to my
Stroustrup v3, this is not valid C++.

Could you please check wether I'm right or not?

Anyway, what should I do with my changes?

Best wishes
Peter Schmitteckert

thank you very much. This was the short term main goal. It isn't open
source without a Linux/gcc port. Unfortunately my team and I are from
Windows/Mac world. We're moving to Linux.

these were our problems

Peter,
         I'm the guilty party for that declaration - and unfortunately I
don't have my Stroustroup here. I'll try and check whether that is legal
code - but if it can be made legal for all compilers by writing it as

         template <int constant>
         class CrankNicolsonTimeSetter {
             enum { isTimeDependent = constant };
         };

just go ahead and do it with my blessing :)

Other issues: first of all, thanks again for the porting (by the way, did
that include the Python module as well?)
On <limits> and <sstream>: they were the main problems also in our
own  attemps (kind of weak ones, actually) to get it to compile with g++.
What I had in mind but didn't have the time to implement was that the use
of sstream should be confined to dataformatters.h/cpp - and there we could
use the good old sprintf instead. Is that what you have done? For what
concerns limits, I had barely started to think about it. But now I guess
I'll just look at your code :)

Bye for now,
                 Luigi
