You are right. I've missed the reason of debian 4.9.2-16 bootstrap
failure described in #c6. It's a stage2/3 comparison failure of
gcc/d/ctfeexpr.dmd.o which means debian adds D lang to FSF GCC tree.
BTW, warnings for cc1*-checksum.o would mean that Adrian's board
enables randomize_va_space feature which I always make it disable
with 'sudo echo 0 >/proc/sys/kernel/randomize_va_space' on my GCC
work. I don't know why/how debian packages D lang together with
the vanilla GCC. It seems 4.9.2-16 could bootstrap without D lang.
