As far as I can tell, this makes scriptlet to set ac_cv_c_inline and then
the result is written to confdefs.h:

    case $ac_cv_c_inline in
      inline | yes) ;;
      *)
        case $ac_cv_c_inline in
          no) ac_val=;;
          *) ac_val=$ac_cv_c_inline;;
        esac
        cat >>confdefs.h <<_ACEOF
    #ifndef __cplusplus
    #define inline $ac_val
    #endif
    _ACEOF
        ;;
    esac

which is used only during the ./configure run but not during the actual
build.

What am I missing?
