Hello!

I'm discovering this project and attempted to run 'make check'.  It
seems to be finding problems, failing with:

--8<---------------cut here---------------start------------->8---
[...]
GPL            ??             lib/xstrtoull.c
GPL            ??             lib/xstrtoumax.c
GPL            ??             lib/gl_xsublist.c
LGPLv2+        GPLv2+         lib/glthread/yield.h
make: *** [Makefile:142: sc_check_copyright] Error 1

Test suite failed, dumping logs.
command "make" "check" failed with status 2
note: keeping build directory `/tmp/guix-build-gnulib-0.1-0.af26171.drv-1'
--8<---------------cut here---------------end--------------->8---

I'm currently using the following dependencies: cppi@1.18 grep@3.4
perl@5.30.2 sed@4.8 texinfo@6.7.

Is this a known problem or is my environment missing something?

Attached is the full log, compressed with gzip.

Also, I had to run the test suite via a single process, as attempting to
run it in parallel would error with this message near the beginning:

--8<---------------cut here---------------start------------->8---
[...]
+$(shell f=$(gnulib_dir)/lib/intprops.h;
+  perl -lne '$(gl_extract_define_simple)' $$f | sort -u | tr '\n' ' ')
+# Remove trailing space and convert to a regular expression:

Thank you,
