I will have a close look at that list!

Because the standard header files for the Amiga OS use 'struct List' and
'struct Node' all though them. Which causes gcc to complain that these
have been redefined. Fortunately these aren't typedef as well.

Here is the error message:
In file included from ../include/nodes/pg_list.h:17,

Thats good to hear.
