But it seems you introdruced or exposed some others. :-(
I can't bootstrap on i686-linux any more:
/cvs/gcc/gcc/libgcc2.c: In function `new_eh_context':
/cvs/gcc/gcc/libgcc2.c:3037: Internal compiler error in `clear_by_pieces', at expr.c:2318
It bootstraps on Alpha and I don't have an x86 cross-compiler handy,
but I do see an error in that function, so please let me know if this
fixes it:
