just open a console in your terminal, put a typo in a source to get an error
(for example line 792 of declaration.d, rename isOverDeclaration ->
isOveDeclaration) and

  $ make -f posix.mak > a.out

I get things like

> ERROR: [1mdmd/declaration.d(792): [1;31mError: [mno property [0;36m[m[1misOveDeclaration[0;36m[m for type [0;36m[m[1mdmd[0;36m.[m[1mdsymbol[0;36m.[m[1mDsymbol[0;36m[m, did you mean [0;36m[m[1mdmd[0;36m.[m[1mdsymbol[0;36m.[m[1mDsymbol[0;36m.[m[1misOverDeclaration[0;36m[m?

Not good.
