What I do is to use the VS console and pass CC and AR on the command 
line as well:

set dm_make=c:\l\dmd2\windows\bin\make
set DMD=../windows/bin/dmd.exe
set cl64=c:\l\vs10\vc\bin\amd64\cl.exe
set ar64=c:/l/vs10/vc/bin/amd64/lib.exe

cd druntime
%dm_make% -f win64.mak DMD=%DMD% "CC=\"%cl64%\"" target
cd ..\phobos
%dm_make% -f win64.mak DMD=%DMD% "CC=\"%cl64%\"" MAKE=%dm_make% 
"AR=\"%ar64%\"" LIB=..\lib64\phobos64.lib

I'm not sure if the mix of forward and backward slashes is necessary. 
Probably not for win64.mak, but for posix.mak which I normally use under 
windows, too.
