The LDC package contains a README.txt. Quoting: 'If run in a 'VS 
Native/Cross Tools Command Prompt' (i.e., if the environment 
variable VSINSTALLDIR is set), LDC skips the Visual C++ 
detection.'

Spawning a new VS command prompt ('shell', cmd.exe with env 
variables set up by the MS batch file) and invoking LDC in that 
shell is the preferred way of skipping that ~1-second linking 
overhead, at least that's how I do things all the time.
If for whatever reason you don't want all of those MS env 
variables, you'll just need VSINSTALLDIR to prevent LDC from 
autodetecting and then the env variables expected by the MS 
linker (LIB and LIBPATH may be enough, I don't remember).
