bug#37312: test failure in sed-4.7

Eric,

Here are the system details:

voodoo03> uname -srv

The GLIBC versions is:

The context is that I am trying to build and test the GCC 9.2.0 compiler,
which was recently released, on a number of different platforms.  Some
platforms have a very old GLIBC (version 2.11.3), so I am also trying to
install GLIBC 2.30.  To do that, I am also installing the linux-5.2 headers,
which also requires a recent version of sed.  Apparently, I need sed to be
successful in making symbolic links before the GLIBC build will work.

Insufficient details - you didn't tell us what your operating system was.
It may be a bug in your libc, or a weakness in the gnulib test that is
trying to determine if your libc is POSIX-compliant.  The correct fix will
be updating gnulib (either to work around your broken libc, or to fix the
broken assumption in the gnulib test), and then releasing a new sed with
updated gnulib.

But in the meantime, how often do you really expect sed to be creating
symlinks?  This is probably safe to ignore in the context of using your
just-built sed.
