      Modifications to the way we calculate CafInfo during tidying (again).
      
      The previous hack of setting the CafInfo on all non-top-level bindings
      to NoCafRefs was a hack, and it came back to bite us: when CorePrep
      floats out a let to the top level it doesn't create a new binding, and
      the existing let binder happens to say NoCafRefs which is unsafe.  It
      was caught by an ASSERT in the CoreToStg when compiling the libraries
      without -O - compiling without -O tends to result in more
      opportunities for CorePrep to float things to the top level.
      
      Now, we calculate CafInfo on the pre-tidied expressions, using the
      mapping from Ids to Ids that is being built up during tidying.  This
      avoids one loop, but will be slightly slower due to the extra lookups.
      However, it means we don't need to set the CafInfo on non-top-level
      binders to NoCafRefs.

      GNU ar seems to have trouble with duplicate object file names if you
      use the 's' modifier, so detect GNU ar here and use a simple 'ar q'
      command to create archives.
      
      This bug was tickled when I replaced an 'ar q' with '$(AR)' in
      target.mk yesterday: the default $(AR) is 'ar clqs'.

      Fix a profiling crash on Windows.
      
      fprint_ccs used snprintf() to avoid overflowing a buffer; on mingw32
      where snprintf() doesn't exist we were just using the straight
      sprintf(), which inevitably lead to a crash.  Rewritten to use a
      homegrown non-overflowing string copying function - it actually looks
      nicer now, anwyay.

      This should have been committed along with rev. 1.36 of Main.c (and
      others) yesterday, but for some reason it got left out.
      
      Change the way Main.main is run, so it now doesn't force the return
      value.  Now 'main = return undefined' will run and exit successfully.
      
      The change affects finalizers too - but since they have type IO (), it
      won't do any harm not to evaluate the ().

      Haskell quiz:  what should this program do?
      
        main = return undefined
      
      answer: run to completion and exit successfully.  GHC erroneously
      evaluates the returned value from main, which causes this example to
      fail with an uncaught exception (the evaluation is even done outside
      of the main exception handler!).

      Use STK_CHK_NP rather than STK_CHK_GEN in the entry code for AP and
      AP_STACK thunks.
      
      The reason is that if the check fails, on return the closure might
      have been blackholed (perhaps due to lazy blackholing, or even because
      another thread has entered it), so we *must* enter the closure to
      continue, rather than just continuing at the original entry point.
      
      All compiler-generated thunks do this anyway, I think these are the
      only cases of thunks which don't follow the rule.
      
      Thanks to Robert Ennals for spotting, and correctly diagnosing, the
      bug.
