That was a typing accident. They were not there.

This is actually 3.11, but menu.c32 from current git behaves the same, 
so I have no reason to believe anything changed.

I tracked the problem down through fgetc() to _fread() to read(), which 
is extern'ed. Removing from _fread() read and returning EOF results in 
successful boot.

Any ideas where to go from here? Is it klibc?
