../../gcc/gcc/config/arm/linux-eabi.h:79:36: error: identifier "not" is a
special operator name in C++

/* Clear the instruction cache from `beg' to `end'.  This is
   implemented in lib1funcs.asm, so ensure an error if this definition
   is used.  */
#undef  CLEAR_INSN_CACHE
#define CLEAR_INSN_CACHE(BEG, END) not used

I've classified this as a target bug, but it is not clear that this error
should trigger if the macro is not used.
