Currently only the Atari has an implementation for lseek, and it uses numeric
values. However, for consistency, I would probably add stdio.inc for use with
assembler files.

Ok, added.

From the Linux manual pages:
O_CREAT
If the file does not exist it will be created. [...]
O_TRUNC
If the file already exists and is a regular file and the open
mode allows writing (i.e., is O_RDWR or O_WRONLY) it will be
truncated to length 0. [...]
[...]
creat is equivalent to open with flags equal to O_CREAT|O_WRONLY|O_TRUNC.

I'm currently reconsidering the decision that lead to using fcntl.h. When
using fcntl.h, I didn't realize that it would contain a larger number of
function prototypes. Now it seems that more and more functions pop up that
would fit into unistd.h. I don't have much time currently to work on cc65,
this will change some time in february. Until that time, I have no chance than
to add that topic to my ever growing TODO list:-)
