            Bug ID: 98311
           Summary: libcody configure checking problem
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

Yesterday's build was fine, today's not.

I get

configure:2624: result: ok
configure:2653: checking bugurl
configure:2670: result: github.com/urnathan/libcody
configure:2690: error: unknown check "df,extra,fold,rtl,yes"

Down in libcody/configure is

case $enable_checking in #(
  yes|all|yes,*) :
    nms_checking=yes ;; #(
  no|none|release) :
    nms_checking= ;; #(
  *) :
    as_fn_error $? "unknown check \"$enable_checking\"" "$LINENO" 5 ;;
esac
