Hi,

As mentioned in
<https://lists.gnu.org/archive/html/bug-gnulib/2025-07/msg00083.html>,
there is an "epsf.tex not found" error during "make distcheck".

The best available fix (now) is to pull epsf.tex from gnulib, and include
it in the tarball. The attached patch does this, and it fixes "make distcheck".
