Is that right? I always thought that syntax-check runs only over the
files that are in the git and not generated ones:

libvirt.git $ git clean -fxd; mkdir _build && cd _build && \
  ../autogen.sh --prefix=${PWD} && echo "" >> libvirt.spec && \
  make syntax-check ; echo $?

0

Whereas:

libvirt.git $ git clean -fxd; mkdir _build && cd _build && \
  ../autogen.sh --prefix=${PWD} && echo "" >> ../libvirt.spec.in && \
  make syntax-check ; echo $?

../libvirt.spec.in
maint.mk: empty line(s) or no newline at EOF
make: *** [../maint.mk:929: sc_prohibit_empty_lines_at_EOF] Error 1
2
