[En-Nut-Discussion] Error compiling Ethernut-4.2.1 on OSX

[Ernst Stippl]

Hi!

That's a known compiler error. I divided the long switch statement in
usart.c into two, then it compiled correctly. 

regards
ernst

That solved a lot of compilation errors.

But now the compiler (4.0.2) aborts with an internal error:

usart.c:821: error: unable to find a register to spill in class
'BASE_POINTER_REGS'
usart.c:821: error: this is the insn:
(insn 653 159 160 14 (set (mem:HI (plus:HI (reg/f:HI 28 r28)
                 (const_int 1 [0x1])) [32 S2 A8])
         (reg:HI 24 r24)) 12 {*movhi} (nil)
     (nil))
usart.c:821: internal compiler error: in spill_failure, at reload1.c: 
1872
