Well actually I meant the shapeshifting about other basic types
like "int" and perhaps "char". That has somewhat travelled into
c++ IIRC but I am not too deep into this to remember anything
special about. The c++ suite does support variants of that AFAIR.

Yepp, the win32 kernel is largefile but the win32 libc does not expose
it in the same and easy way as unix98-compatible platforms do. Didn't
we had that topic already? Ah, right, there it is where that impression
came from...
