Marshel, that patch does not address the ambiguity created by backwards
compatibility with glibc 2.0.6, it merely removes the backwards compatilibility
(while retaining notes that it is compatible). You also omit the return value
in your return statement.
I'd be happy with the backwards compatibility removed (and a note to that
effect), given glibc 2.0 is now 15 years old. The code could then be
simplified. At the time I encountered this issue, I wrote the following code,
which would just error out in the case of truncation with old glibc.
