Re: [PATCH] Autoconf: Disable inline for compilers that don't support it.

Allan Caffee [off-list ref] writes:

The Autoconf macro AC_C_INLINE will redefine the inline keyword to whatever the
current compiler supports (including possibly nothing).

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?
