In all these cases you get a message about `get_safe_registers', i.e. another 
error; do you get the error about __bb_init_func with the "try removing" 
thing?
Also, it should compile by disabling CONFIG_GCOV (as you know probably), and 
this option is only for debugging - if it does not compile in that case 
there's something _very_ strange going on (like if `get_safe_registers' had 
been removed by hand-editing); anyway this discussion is useful to find the 
fix to the bug.

No, don't undefine it. I was talking about this error message, which I can't 
explain - I thought it was just a conseguence of the error above.

since get_safe_registers is defined in arch/um/os-Linux/sys-i386/registers.c, 
this error does not make a lot of sense. Make sure you haven't removed the 
definition by mistake - the other possibility is that file is not linked with 
the rest, but this would cause also other "undefined reference" errors.
