[Click] FreeBSD 6.0

[Eddie Kohler]

Hi Andrew,

Our FreeBSD kernel support tends, unfortuantely, to rot quickly, as I don't 
believe anyone uses it day to day.

The "invalid conversion from `void*' to `T*'" errors can probably be fixed 
with -fpermissive.

The last errors are maybe more serious, and indicate an interface difference 
between 5.0 (which is what we currently more or less support) and 6.0.  I 
don't know what to do there.

We'll accept any patches that make this situation better!
Eddie
