You must be looking on the 'master' branch. Unlike most other git repos,
for GNU m4, the current development takes place on the 'branch-1.4' branch,
not on the 'master' branch:
https://git.savannah.gnu.org/gitweb/?p=m4.git;a=shortlog;h=refs/heads/branch-1.4

Yes, this is a known issue. For this reason, we are offering snapshot
tarballs (built from aforementioned branch, together with gnulib 'master').

The newest created (snapshot) tarball is available through the Gitlab UI
https://gitlab.com/gnu-m4/ci-distcheck
 > CI/CD > Jobs > Finished (check-optimized)
 > Job artifacts > Browse > m4-snapshot.tar
or directly through the following command sequence:
  wget -O m4-snapshot.tar 
'https://gitlab.com/gnu-m4/ci-distcheck/-/jobs/artifacts/master/raw/m4-snapshot.tar?job=check-optimized'
  tar xf m4-snapshot.tar
