That is useful information in general, I did not know about
core.stdc.config and it is useful in future projects!
But for my project the C works at 64 bits except on Windows for
the reason you gave. So by translating long in C to long in D it
loses 32 bits but gains 64 bits on Windows. This is what I want.
