Thanks, I forgot about the symlink I made at the time of submitting. Applied and tested this, cleaned up port, attached. > Also, I would prefer the port to work with the in-tree compiler. Does that mean the core CVS tree, as opposed to ports and packages? Right now it works with 8.4.0 that is in the ports tree. I understand you'd prefer it to work with /usr/bin/cc. There are many (types of) errors and warnings that that compiler throws. I appears to me that the code could use improvements. I have not been able to reach the author and I have to consider if I have sufficient time and skills to patch it up. Marco
