thanks for explaining the issue. I've got this from a book called learn c++
in 21 days (as I already have a good experience in C and perl objects) it's
really not hard to progress
Well part of the question (or the main point was) why it's working in 4.2
and not in 4.3
thus suddenly it won't compile. To me it does not look like a change made 11
years ago but yesterday also I know the .h at the end is wrong but it's
compiling with 4.2.
I would like to be able to compile my code in the future that's all.
I don't like somebody to decide on behalf of me if I should port my code or
not. This is called integrity and compatibility and the present situation
is absolutely not reliable.
