13 | # For consistency with gcc, we do not adopt Sun Marketing's |
14 | # removal of the '2.' prefix from the Solaris version number. |

18 | # If perl fails tests that involve dynamic loading of extensions, and |
19 | # you are using gcc, be sure that you are NOT using GNU as and ld. One |
20 | # way to do that is to invoke Configure with |
