Most of these troubles should go away if you use the 'compile' and 'ar-lib'
auxiliary scripts, as described in section 2 of
These instructions were tested with GNU gperf and a couple of other GNU
packages. They should be applicable to GNU gzip as well.

It is in this step 'c' that the 'compile' auxiliary script becomes useful.
