Well spotted. We probably should add something like this
as a syntax check:

  { sed -n '/^\/lib\/.*\.h$/{p;p}' .gitignore;
    find lib -name '*.in*' ! -name '*~' ! -name 'sys_*' |
      sed 's|^|/|; s|_\(.*in\.h\)|/\1|; s/\.in//'; } |
  sort | uniq -u

Which currently suggests adding these to .gitignore:

/lib/arpa/inet.h
/lib/errno.h
/lib/float.h
/lib/fnmatch.h
/lib/netinet/in.h
/lib/pthread.h
/lib/sched.h
/lib/se-context.h
/lib/se-selinux.h
/lib/stdarg.h
/lib/stdbool.h
/lib/stddef.h
/lib/stdint.h

cheers,
Pádraig.
