Warning, ABI breakage from 2.074 to 2.075

[Jason King via Digitalmars-d]

That’s a fairly important requirement if it’s supposed to be a systems
programming language, less so for application focused stuff.  I would hope
it’s at least an eventual goal even if it’s not quite the case today.

Why is this unexpected? D has never committed to ABI stability
across compiler versions or the different D compilers.
