Syntax mistakes

I downloaded OpenCascade 5.0 using the multiple file download. I tried to compile the TKDraw library, but the code has a lot of syntax mistakes. It seems like parts of the source code are missing. Example:

class BOPTools_DSFiller {
public:
void* operatoOPTools_SplitShapesPool;
cl)
{
return anAddress;
}

What is the "cl)" doing there ?

Need help.

Regards,
Timo
