help the compiler create more efficient code Patch from Michael <virtual_worlds@gmx.de> Full text: As usual I have modified only minor things to remove warnigs when compiled as C++ code, have added some const-specifiers where possible to help the compiler create more efficient code and added some static-specifiers to make functions invisible to other modules.
