Yeah, I suppose that ought to be its own separate patch, in that
case.

It’d be a step in the direction of making the testsuite run cleanly
with -Wstrict-prototypes and/or -Wold-style-definition, which might
plausibly help with the related effort to support compilers that
reject old-style definitions.  But I agree that it’s not a high
priority and shouldn’t block this patch.
