[PATCH] Fix for Bug 5053

[Reid Kleckner]

It is supported, but in a very roundabout way, unfortunately. You have to
use a target triple like: i686-pc-windows-msvc-elf or something ridiculous
like that. Try adding '-mtriple=i686-pc-windows-msvc-elf'. MCJIT has a lot
of loader-like functionality, but it's only implemented for MachO and ELF,
not COFF, so you have to emit and "load" ELF files in memory to use MCJIT
on Windows.
