One further question is whether functions under
'xen/common/coverage/gcov_base.c' should gain
a declaration in 'gcov.h' or not, as they exist just for the purpose
of
being referenced
by autogenerated profiling code. I see no reason why they shouldn't,
but
they can also be safely deviated,
since they are not called by Xen code.
Imo it should be the compiler to provide a prototype for these (much
like it does for builtins), thus ensuring that an implementation
actually matches the compiler's expectations. Yet afaics it doesn't.

Then it's perhaps best to deviate them.
