I read this and browsed the source back and forth and to be honest I'm
more confused than before. ;)

Let's make it specific:

If I want to add a missing function from libc to the right unit, how
would I?

Do I have to fiddle with what's called "assembler aliasing" in any way
or do I declare as "external libc"?

How do I find the right unit or include file to stick it in?

I'm talking about the function "readdir_r" existing at least on bsd's
and on newer linux.

(btw. the wiki has improved very much in this area, good work)
