This is not correct. GHC, the de facto Haskell compiler, targets an intermediate language called C--, which resembles but is not identical to C and was explicitly designed as a compiler target. The point that some languages do compile to other high-level languages is true—Nim and Haxe being some good examples—but it is not true of Haskell.

> The C code generator is only supported when GHC is built in unregisterised mode, a mode where GHC produces “portable” C code as output to facilitate porting GHC itself to a new platform. This mode produces much slower code though so it’s unlikely your version of GHC was built this way. If it has then the native code generator probably won’t be available. You can check this information by calling ghc --info (see --info).
