 OK, I'll reclassify it.

 Well, I'm not sure we wanted a -Wpossibly-misoverloading (which may
 include overloads that are not overrinding) than a
 -Wmissing-declarations.  It is /typical/ in C++ to define a "global"
 (mor accurately a nemspace-scope) function with no preceding
 declaration.  The -Wmissing-declarations is much about detecting
 "auto-prototyping" function use than detecting mis-overloading.
 
 I would suggest we keep separate these two separate issues.
