You have me eating humble pie.  The standard requires static_cast to obey 
access controls.  Full marks to you, and there are a lot of non-compliant 
compilers out there, and probably quite a lot of code broken by the standard 
now being complied with by gcc.  (However, you are a brave man basing your 
findings on an unreleased version of gcc.)

I wonder if the relevant private derivation in gtkmm needs to be reviewed.  
reinterpret_casts generally seem like desperation, and changing the access 
type of the derivation seems a preferable way of ensuring compliance with the 
standard.
