[Yhc] Compiling Prelude.hs

[Thomas Shackell]

Hi Krasimir,

Great work with the .NET backend!

It wouldn't be easy. Knowing whether a function internal to this module 
is primitive is relatively easy. However knowing whether a function in 
another module is primitive is harder because the program gets it's 
information about external functions from the .hi file and the .hi file 
doesn't store whether a function was primitive or not.

It would be possible to add it, but messing about with the hi files 
isn't fun (trust me ;-)).

Hope that helps

Tom
