# step 1: make a backup of your existing gcc cache you'll lose things like libstdc++
# step 2: modify sorcery CFLAGS to be generic x86_64 only
# step 3: cast -r gcc -> select c and ada
# step 4: wait
# step 5: after it's done copy the generated cache(named gcc-$VERSION-$HOST.tar.bz2)
#         to ada-$VERSION-$HOST.tar.bz2
# step 7: update version under the right field and test cast gcc with ada enabled
# step 8: cast something ada dependant AND RUN IT
# step 9: if it all works then upload the cache generated under step 5 somewhere
#         bug someone to put it in the right place if you don't have access
# step 10: restore your old gcc cache and resurrect it
