An issue with unlocked-io.h and bootstrapping.

[Mats Erik Andersson]

Hello,

I have made a strange observation concerning

    lib/unlocked-io.h

which appears when running the bootstrap script
for GNU Inetutils.

Until very recently, "unlocked-io" was included
as a dependency in our "bootstrap.conf". Upon my
complaint, Alfred M. Szmidt remove that entry,
after which the following issue vanished completely.
Therefore we suspect there be a bug in GNUlib on
this matter.

Now, running "bootstrap" on a fresh cheackout of
GNU Inetutils, and then happily running

   rsync -Ca . ../temp/

one would expect a source tree where configuration and
compilation works. Right? But alas, it does not.

An empty soft link

    lib/unlocked-io.h

remains, which is pointing at the non-existent
location

    ../gnulib/unlocked-io.h

Performing a full copy, or using tar/cpio pipes,
will of course work, but not the pruning incvolved
in "rsync -Ca".


Best regards,
Mats Erik Andersson (member of GNU Inetutils)
