On Alpine Linux 3.24, I see two test failures:


FAIL: src/preproc/eqn/tests/neqn-finds-matching-eqn.sh
======================================================

/home/bruno/groff-1.25.0.rc2/build-64/neqn: exec: line 56: @g@eqn: not found

GNU eqn (groff) version 1.25.0.rc2
FAIL src/preproc/eqn/tests/neqn-finds-matching-eqn.sh (exit status: 1)

FAIL: src/preproc/eqn/tests/neqn-smoke-test.sh
==============================================

/home/bruno/groff-1.25.0.rc2/build-64/neqn: exec: line 56: @g@eqn: not found

FAIL src/preproc/eqn/tests/neqn-smoke-test.sh (exit status: 1)


Indeed, line 56 of the generated 'neqn' script looks like this:

  exec @g@eqn -T ascii "$@"

The reason is that the 'sed' program on this platform (from BusyBox)
ignores '-e' options when a '-f' option is present, regardless whether
the '-e' options come before or after the '-f' option.

Here's a proposed fix.

Verified by manually modifying the Makefile accordingly. (I can't regenerate
a snapshot tarball for testing, because of the missing epsf.texi problem
<https://savannah.gnu.org/bugs/?68566>).

Subject: [PATCH] build: Fix generation of 'neqn' script on Alpine Linux.

* src/preproc/eqn/eqn.am (neqn): Use two separate 'sed' invocations, as
BusyBox 'sed' ignores '-e' options if a '-f' option is present.
