/* 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.

Could you specify which version of the source tree this was ?

This is trunk, version 147956 or later.  Using not_used instead of "not 
used" would suffice to fix this, but the -Wc++-compat warning probably 
should be smarter; there's no need to care about the expansions of unused 
macros like this.

I changed the define in my tree to "NOT USED" to avoid this.
