The MinGW ones for the Windows API may do, but the VS 2010 
libraries are not an option for LDC, we require at least 2015 
(which introduced the 'Universal CRT', probably making things 
more complicated). I'd also prefer to keep on defaulting to the 
static C runtime in order not to produce binaries depending on 
Visual C++ DLLs (hindering portability of Windows binaries).
