By default, DMD uses the Optlink linker and some quite old system
import libraries in the OMF format. They’re missing a number of
functions. If you compile with -m32mscoff for 32-bit or -m64, DMD
will use the Microsoft linker and import libraries if you have
Visual Studio or the MS Build tools installed, and the LDC linker
with some import libraries from MinGW if you don’t.
