What Dub does is what it calls "platform probing" [3]. It
creates a temporary .d file containing various `pragma (msg,
..)` statements that output information to stderr during
compilation. Of course the question is then: which compiler is
used to compile the platform probe file? AFAICS, it uses either
the one requested for on the command-line (via --compiler=... )
or via an internal heuristic which is a bit involved [4].
FYI: the plan is to use the new JSON interface (e.g. `dmd
-Xi=compilerInfo -Xf=-) soon.
