This branch contains an 'ar' emulation (file 'ar-lib'). Good.
But how is the file 'compile' meant to be used? CC="compile cl"
or how? In other words, if I set CC="cl", how are autoconf tests
that run the compiler meant to be performed?

People routinely use a program called 'cccl' in
  $ ./configure CC=cccl
See [1].

Will that functionality be moved from 'compile' to a script like
'cccl' at some point?
