What's the output of dmd --version?  I find it extremely odd that .dig
isn't supported.  AFAIK, it's been there since the early days of D.
Certainly, it has been there since I started using D, which was before
dmd was ever available in Debian.

What's the compiler output of:

	pragma(msg, float.dig);

?
