Are you sure the initialisation to 0 can be removed ? Usually 
initialisation to 0 is not needed because not initialised variables go in 
the BSS section which is zeroed at startup. But here the variable is 
flagged with __force_data so it is not going in the BSS section.

Any non-automatic (i.e. function-scope, not static) variable is
initialised to 0.  See e.g. C11 6.7.9/10 (this has been like that since
times immemorial, C90 anyway).
