8 | # For consistency with gcc, we do not adopt Sun Marketing's |
9 | # removal of the '2.' prefix from the Solaris version number. |
10 | # (Configure tries to detect an old fixincludes and needs |
11 | # this information.) |

13 | # If perl fails tests that involve dynamic loading of extensions, and |
14 | # you are using gcc, be sure that you are NOT using GNU as and ld. One |
15 | # way to do that is to invoke Configure with |
73ad924b |

17 | # sh Configure -Dcc='gcc -B/usr/ccs/bin/' |
18 | # |
19 | # (Note that the trailing slash is *required*.) |
20 | # gcc will occasionally emit warnings about "unused prefix", but |
21 | # these ought to be harmless. See below for more details. |
