Re: autoconf 2.13 does not recognize the correct executable extension

[Akim Demaille]

Autoconf CVS has solved this by explicitly including *.C.  

      case $ac_file in
      *.c | *.C | *.o | *.obj | *.xcoff) ;;
      *) ac_cv_exeext=`echo $ac_file | sed -e s/conftest//` ;;

Using *.ac_ext sounds good, but it means we have to AC_REQUIRE it
beforehand.

I have no strong opinion on this.
