Building DMD on windows - wiki is outdated

[ryuukk_]

The wiki seems to need an account to be able to edit it

Can someone with an account with proper editing rights and who is 
knowledgeable about building DMD check what needs to be updated?

All i know is druntime was moved to the dmd repo, so this step 
should be removed

For the rest i'm not sure, i see mentions of ``make`` but there 
is no ``make`` for windows
