compiler warnings

[holgerfriedrich]

Compiling code using bgslib headers issues a lot of warnings especially at high warning levels. I care especially for the warnings issued when using the headers, not so much for the ones wen compiling the library. Many of them could be resolved easily.

What is you policy on that? Never change imported files to be able to upgrade them to new release from the author? Or should I just put a pull request?
