gnulib distcheck test failure

[Ralf Wildenhues]

Hello Bruno, all,

gnulib-tool --with-tests --test  # interrupt at convenient location
.../configure
make check                       # passes, but:
make distcheck

fails because GNU make puts the wrong test-fprintf-posix.out file in the
tarball.  This is due to a builtin pattern rule `%.out: %' that causes
this file to be a copy of the binary test-fprintf-posix on GNU/Linux,
generated in the build tree, rather than taking
$(srcdir)/test-fprintf-posix.out (which has an older time stamp than
test-fprintf-posix).

Adding manually to gltests/Makefile.am the rule:

test-fprintf-posix.out:
        @:

fixes this, and makes `distcheck' pass again, but it should be added once
only, not once for each test that uses the .out file.  Use a new module
for this?  Not sure if it's worth the hassle.  We could simply rename the
file instead.

Cheers,
Ralf
