The frontend is automatically deducing things like @nogc and
nothrow, but it is flaky and results in linker errors for a
complex codebase (Weka's).
What happens in that in one kind of compilation, @nogc is deduced
for a function. But in another compilation, it isn't. Thus
references to the function will have the wrong mangling, and
linker errors happen:

This is blocking upgrading to a newer compiler with a newer
frontend (2.071 --> 2.073).
(I already have a large amount of work arounds... Also non-user
functions have this problem, e.g. there is a nothrow deduction
problem for __fieldPostblit.)
Thanks for looking into this bug.
