Comment (by nr):

 Replying to [comment:9 simonmar]:

 I certainly didn't mean to suggest that you even ''consider'' another
 attack on the build system!  I really was thinking about a student
 ''here'' :-)

 I'm interested in nmake exactly because relative to gmake or standard
 make, nmake definitely requires fewer phase distinctions, and it may
 eliminate phase distinctions altogether.  No phase distinctions -> no
 phase ordering -> speed.  But it sounds like the hacks you've put in will
 help a lot.

   Surely most of the time the dependency file will be there anyway?

 Actually no.  The problem is that I'm propagating a change in the
 representation of low-level intermediate code, and it will be a very long
 time before all the modules in the compiler are once again mutually
 consistent.  And apparently as long as any module does not compile, GHC
 cannot generate the dependency file.  I hope I am wrong about this and am
 just doing something stupid.  Please say I am?

 If I'm not doing something stupid, can you suggest where I might go to
 filter the output of make in my own private world?
