Ok thanks, for now I've changed the functions to use a sufficent known
number of arguments. Is not nice but will work.

Since it is a C program with OO emulation, the compiler generates a lot
warnings about classes defined by macros. Unfortunatly, I have not found the
right switch at the gnu gcc manual page.

Thanks a lot for this nice tool, works great for me :)
Are there any plans to build a new offical release (may be RC) from the
current SVN sources?

Kind Regards
Stefan
