          Issue ID: 19821
           Summary: Cannot pass linker argument with spaces
           Product: D
           Version: D2
          Hardware: All
                OS: Windows
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: doob@me.com

With an empty D file, running the following command:

dmd main.d -L/LIBPATH:"C:\Program Files" -v -m64

Will output, among other things:

/LIBPATH:C:\Program Files

And fail with:

LINK : fatal error LNK1181: cannot open input file 'Files.obj'

The problem is that the path should be quoted because it contains spaces.
