Shouldn't this conversion be automatable?

Failing this, IMHO all math functions that don't already (I'm not sure how
many don't) should have a portable implementation (which could be just
calling C) that meets all requirements (safe, pure, nothrow, etc.).  This
would be "good enough" until someone gets around to writing optimized ASM
versions of the math functions, and would probably make it easier for the
GDC/LDC people to port D to more archs.
