attributes will make programmer's lives hell (unreadable crap).
plus deviation from standard c will make code-conversion that
much more work. to be severely avoided regardless of potential
complaints.

for EUR 50,000 which disappears on embecosm's budget in under

phase will be firmly out of scope.

if however other devs help out rather than complain then i have
absolutely no problem at all.
