This should be:

[...]

  { printf "%s\n" "$as_me:${as_lineno-$LINENO}: checking whether MB_CUR_MAX is 
correct" >&5
printf %s "checking whether MB_CUR_MAX is correct... " >&6; }
if test ${gl_cv_macro_MB_CUR_MAX_good+y}
then :
  printf %s "(cached) " >&6
else $as_nop

                  case "$host_os" in
                  # Guess no on Solaris.
        solaris*) gl_cv_macro_MB_CUR_MAX_good="guessing no" ;;
                  # Guess yes otherwise.
        *)        gl_cv_macro_MB_CUR_MAX_good="guessing yes" ;;
      esac
      if test $LOCALE_FR_UTF8 != none; then   ### *** LINE 33322 *** ###
        if test "$cross_compiling" = yes
then :
  :
else $as_nop
  cat confdefs.h - <<_ACEOF >conftest.$ac_ext
