DMD 2.072.1 MSVC build seems to be failing

[Lewis via Digitalmars-d]

I like to build DMD with MSVC because it complies a little faster 
than the shipped executable. I downloaded and installed a fresh 
copy of DMD 2.072.1, opened dmd2/dmd/vcbuild/dmd.sln, and tried 
to build. I got several compilation errors related to missing 
files, in particular:

1>c1xx : fatal error C1083: Cannot open source file: '..\glue.c': 
No such file or directory
1>c1xx : fatal error C1083: Cannot open source file: '..\msc.c': 
No such file or directory
1>c1xx : fatal error C1083: Cannot open source file: '..\toir.c': 
No such file or directory

I tried fiddling a bit with removing these files from the 
project, and I could get the first stage of the build to pass, 
but then I ran into linker errors later on. I don't know enough 
about how this project is set up, so I figured I'd just ask.

Any ideas what's going on? Did the VS project simply not get 
updated for the new release, or am I missing something in my 
build procedure? I can build my old installation of 2.071.0 
without issue.

Thanks!
