"The binaries needed by programs built by these tools...", you're referring to 
the C runtime DLLs?  Why does that matter?

Note I said "with no dependencies" above.  A Windows native port of GHC would 
require you to go to MS and download the assembler and linker separately - we 
couldn't automate that, there are click-through licenses and stuff.

MS pays for Ian Lynagh, who works full time on GHC as a contractor.  MS puts 
roughly as much money into GHC as it does into F#, FWIW.
