LLVM will only generate object files. You will need to link them to get
the final executable. This will determine whether (and if) you need any
special DLLs. If your language allows the programmer to call functions
provided by the OS, or some emulation of Unix's libc, then you will need
to have some sort of a runtime library. In the simplest scenario, the
runtime will simply be the standard Windows DLLs (kernel32.dll, etc.).
