You could use llvm-gcc to convert the struct to an LLVM type.
Otherwise, it wouldn't be too hard to convert the struct by
hand as long as it doesn't have any exotic types in it.  A
VLA at the end (with element type T) is currently represented
by placing a field of type T at the end (i.e. just one element).
