I tried --disable-checking and --enable-coverage, no problems bootstrap
completed. Using --with-gc=zone had some warnings which are fixed below.
I'll try extra --enable-checking options overnight.
Meantime, patch below bootstrapped with --with-gc=zone on
x86_64-unknown-linux-gnu. Okay for mainline?
Thanks,
