[GHC] #729: Build system uses wrong version of include files.

[Simon Marlow]

Can anyone comment further on this bug?  I've forgotten who the 
submitter is, and we need more information.

 From the description, it looks like the installed version of HsUnix.h 
is being used while compiling the compiler, which is correct for the stage1
compiler, but would be wrong for stage2.  Which stage is this?

Cheers,
	Simon
