Subject: Generalized my type flags structure extension without being specific about
X-Git-Tag: v2.3c1~633

Generalized my type flags structure extension without being specific about
the purpose. Increased my claim to two bits, hoping that nobody
will complain about it. I'm taking the highest two bits, whatever
the integer word size may be.
