config.log contains nothing interesting:

configure:3207: checking whether sys/types.h defines makedev
configure:3223: gcc -o conftest -g -O2   conftest.c  >&5
configure:3223: $? = 0
configure:3232: result: yes

The test implemented by AC_HEADER_MAJOR is simple: it just tries to compile and
link "makedev(0, 0)".

Here is the relevant part of generated configure script (with empty lines
removed for brevity):

{ $as_echo "$as_me:${as_lineno-$LINENO}: checking whether sys/types.h defines
makedev" >&5
$as_echo_n "checking whether sys/types.h defines makedev... " >&6; }
if ${ac_cv_header_sys_types_h_makedev+:} false; then :
  $as_echo_n "(cached) " >&6
else
  cat confdefs.h - <<_ACEOF >conftest.$ac_ext
/* end confdefs.h.  */
int
main ()
{
return makedev(0, 0);
  ;
  return 0;
}
_ACEOF
if ac_fn_c_try_link "$LINENO"; then :
  ac_cv_header_sys_types_h_makedev=yes
else
  ac_cv_header_sys_types_h_makedev=no
fi
rm -f core conftest.err conftest.$ac_objext \
    conftest$ac_exeext conftest.$ac_ext
fi
{ $as_echo "$as_me:${as_lineno-$LINENO}: result:
$ac_cv_header_sys_types_h_makedev" >&5
$as_echo "$ac_cv_header_sys_types_h_makedev" >&6; }
if test $ac_cv_header_sys_types_h_makedev = no; then
ac_fn_c_check_header_mongrel "$LINENO" "sys/mkdev.h" "ac_cv_header_sys_mkdev_h"
"$ac_includes_default"
if test "x$ac_cv_header_sys_mkdev_h" = xyes; then :
$as_echo "#define MAJOR_IN_MKDEV 1" >>confdefs.h
fi
  if test $ac_cv_header_sys_mkdev_h = no; then
    ac_fn_c_check_header_mongrel "$LINENO" "sys/sysmacros.h"
"ac_cv_header_sys_sysmacros_h" "$ac_includes_default"
if test "x$ac_cv_header_sys_sysmacros_h" = xyes; then :
$as_echo "#define MAJOR_IN_SYSMACROS 1" >>confdefs.h
fi
  fi
