  New Revision: 36071

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=36071

  Log:
    * configure.in: use -fbuiltin with -ansi -std=iso9899:199409.
      This prevents errors introduced by disabling bulitin functions,
      which is the sub-effect of -ansi/-std.
      Now NetBSD can use -ansi -std=iso9899:199409.
      Maybe mingw, cygwin and darwin can also.
