for the jumping distribution).

- remove unused argument of the DLL
- fix documentation inside source file

Preprocessor: fix line numbering problems due to native MATLAB statements (bug introduced in a0cd4b33 and 65823417)

Reference manual: no longer needed to install MSVC runtime for Win64, since we now compile with MinGW64

Build system: fix bug for compilation with mingw 64-bit (linking with MSVC export files creates MEX files which crash, while directly linking with the DLL binary works)
