no-dist-gzip? What I was saying: you do not have to run make dist.
You could run make dist-bzip2 instead. Producing one files as a side
effect of build system is one thing, but uploading them to a public
required manual intervention.

Woha, that's long. I take the freedom to usually do it within two

Well, compression always takes time. If you wanted to go for
the best compression-to-time-ratio, you would have to go with
uncompressed as the premium.

Now how many Windows users can actually run shell scripts (as
produced by autotools) out of the blue, without having, uh, a shell
(from cygwin or msys). Once they however have such a unix layer, they
also have tar and gzip at least.
