It's possible. In what way to you think we may be using access() incorrectly?

By the way: A good place for brltty-specific stubs would be in sys_grub.c. 
That, for exaple, may be a good place for an atexit() which will meet brltty's 
specific needs. I can add attexit() there. If there are any other stubs which 
you'd prefer be specifically part of brltty, rther than part of grub in 
general, please let me know what they are and where I can find your current 
implementations of them.

I can also add your charset_grub.c and usb_grub.c to brltty now, if you'd like.

It looks like -DGRUB_FILE=__FILE__ will work.
