I was just trying out using it directly in the .d file without 
importing core.stdc.math. I am able to use HUGE_VAL in the .c 
file (so not a bug that way). The c math header should be setting 
HUGE_VAL based on a preprocessor macro (on WSL I assume it should 
run automatically). I was assuming that importC would re-write 
that to an enum that I could use directly in the D file, but the 
spec says that it doesn't support all uses of metaprogramming 
with these. You think that's what I'm running into?
