That's why writing a sanitizing thin layer in C is a way to go. There
is no need to standardize every corner of all languages, it is enough
to standardize their "common denominators".

Note also that ABI is only part of the problem, so solving it would
not be enough. Other important problems are in name overloading,
templates and exceptions. It is not even clear if standardizing these
at the bit level would be beneficial, because having some
implementation freedom in there ensures a competition opportunity for
compiler writers.
This is exactly the same in Ada, by the way.
