11 | # Contact dfavor@corridor.com for any of the following: |
12 | # |
13 | # - AIX 43x and above support |
14 | # - gcc + threads support |
15 | # - socks support |
16 | # |
17 | # Apr 99 changes: |
18 | # |
19 | # - use nm in AIX 43x and above |
20 | # - gcc + threads now builds |

21 | # [(added support for socks) Jul 99 SOCKS support rewritten] |

23 | # Notes: |
24 | # |
25 | # - shared libperl support is tricky. if ever libperl.a ends up |
26 | # in /usr/local/lib/* it can override any subsequent builds of |
27 | # that same perl release. to make sure you know where the shared |
28 | # libperl.a is coming from do a 'dump -Hv perl' and check all the |
29 | # library search paths in the loader header. |
30 | # |
31 | # it would be nice to warn the user if a libperl.a exists that is |
32 | # going to override the current build, but that would be complex. |
33 | # |
34 | # better yet, a solid fix for this situation should be developed. |
