You need speed.exe on Windoze.

  Oddly enough, if I run 'make tune' then there's no need to modify the
  original Makefile - though 'make tune' subsequently fails to compile
  after a while.
  I'll make this the subject of another bug report after this one has
  been sorted.
The target tune is a meta target.  To build tuneup.exe, you need "make

  In case the 'make tune' output throws some light on the problem with
  make speed' here's how 'make tune' terminates:

We never ported timing things to WinDoS.

One should not need to run any of the things in tune/ on non-Unix
platforms.  The important thing is to run it on each CPU type.
