Executable size?

[apologies to anybody who sees the rather similar message I posted to caml-list...] How does Haskell (ghc) compare with languages like O'Caml, C and C++ for executable size? How big is the runtime library? Are there any easily-identifiable, non-obvious, factors that affect executable size (I'm talking about end-use factors, rather those resulting from the design decisions taken by the language designers and implementors)? I currently use Python by preference, but I'm interested in a language (other than C/C++!) that doesn't depend on a big runtime library and generates "reasonably" small executables -- modems are here to stay for a while yet. Thanks for any help John
