30 | # The two flags "-fpic -DPIC" are used to indicate a |
31 | # will-be-shared object. Configure will guess the -fpic, (and the |
32 | # -DPIC is not used by perl proper) but the full define is included to |
33 | # be consistent with the FreeBSD general shared libs building process. |

35 | # setreuid and friends are inherently broken in all versions of FreeBSD |
36 | # before 2.1-current (before approx date 4/15/95). It is fixed in 2.0.5 |
37 | # and what-will-be-2.1 |

125 | Some users have reported that Configure halts when testing for |
126 | the O_NONBLOCK symbol with a syntax error. This is apparently a |
127 | sh error. Rerunning Configure with ksh apparently fixes the |
128 | problem. Try |
129 | ksh Configure [your options] |
