Here is the first public preview of the source translation of lossyWAV 1.3.0 to C++. It is not finished, but the main work is done.

- vc10_err.txt list the current compiler output in Visual Studio C++ 2010.
- A number of built-in Delphi functions are not yet converted. Most are trivial, but Write() involves some work.

Please note, I know very little of how the code actually works, I basically translated it line by line, and did minor optimizations.
Developers can look over the code and compare with the Delphi source. I have tried to take into account a number of C++'s quirks, e.g.:
- integer / integer -> integer (not floating point, but if one operand is float, it returns float)
- unsigned int (opr) signed int -> unsigned int
- & is bitwise-and, && is boolean-and, likewise with or: |, ||
- c++ base 0 arrays, versus base X in delphi. (range_array class in nSupport.h emulates that)

Optimizations:
* var = var opr value --> var opr= value;
* var = var + 1 --> ++ var;
* and a few more

I added file nSupport.h that has a few Delphi emulation functions and classes. The shared global variables are only declared in the header file. I've not defined them in the cpp files yet.

Thanks Tycho.

I''ve got it to compile with Dev-CPP. It doesn't't like strings inside structures and parameter passing was a bit tricky. I''ll post a revision in the development thread when I have something worthwhile to contribute.
