Robin Stuart b3a1b24d18 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.
