It's not only legal, it's a good way to hide function names from
other modules.  A function need not be visible globally in order
to be called from other modules.  (The only need for global
visibility is to permit external linkages to be resolved by the
link editor; in your case there are no such linkages.)

I won't guarantee that all C implementations handle this
correctly, but it's an implementation bug if one doesn't.
(I don't know of any C implementations that can't handle this.)
