[BRLTTY] BRLTTY in GRUB2

Tue Apr 3 23:02:53 EDT 2012

Rather than defining HAVE_FLOAT, please change to defining NO_FLOAT. The code 
in notes, beeper, pcm, midi, and fm has been changed to work with integers if 
NO_FLOAT is defined.

INT16_MAX isn't defined. Probably all the signed standard integer macros should 
be defined.

Does Grub have functions for sounding the PC speaker beep?

Does Grub have functions for reading and writing I/O ports?
