I think the buffer overflows are due to a recent change in our c lib... this is one of those things that needs some one to go throught the Contrib and make sure everything is correct... Time consuming and Time best spent on the OS rather than the contributed programs. :-(
As for Porting, I suggest you join the AROS-Dev mailign list, the guys on there would be happy to tell you have to port your software to AROS/AmigaOS :-)
