Thanks for catching that.

Huh.  gl_CHECK_NEXT_HEADERS invokes AC_CHECK_HEADERS under the hood.  That 
means several other .m4 file can probably be simplified:

m4/arpa_inet_h.m4
m4/getopt.m4
m4/langinfo_h.m4
m4/sched_h.m4
m4/spawn_h.m4
m4/sys_file_h.m4
m4/sys_ioctl_h.m4
m4/sys_socket_h.m4
m4/sys_times_h.m4
m4/sys_utsname_h.m4
m4/sysexits.m4
m4/unistd_h.m4
m4/wchar.m4
m4/wctype.m4
