Only change in revision 2 is to Patch 3: adding 'execWorkmem.c' to
meson.build. As I use gcc "Makefile" on my dev machine, I did not
notice this omission until CFBot complained.
I bumped rev numbers on all other patches, even though they have not
changed, because I am unfamiliar with CFBot and am trying not to
confuse it (to minimize unnecessary email churn...)
Anyway, the patch set Works On My PC, and with any luck it will work
on CFBot as well now.
