5 | # AIX 4.1 hints thanks to Christopher Chan-Nui <channui@austin.ibm.com>. | |
6 | # AIX 4.1 pthreading by Christopher Chan-Nui <channui@austin.ibm.com> and | |
7 | # Jarkko Hietaniemi <jhi@iki.fi>. | |
8 | # AIX 4.3.x LP64 build by Steven Hirsch <hirschs@btv.ibm.com> | |
9 | # Merged on Mon Feb 6 10:22:35 EST 1995 by | |

12 | # Contact dfavor@corridor.com for any of the following: | |
13 | # | |
14 | # - AIX 43x and above support | |
15 | # - gcc + threads support | |
16 | # - socks support | |
17 | # | |
18 | # Apr 99 changes: | |
19 | # | |
20 | # - use nm in AIX 43x and above | |
21 | # - gcc + threads now builds | |
22 | # [(added support for socks) Jul 99 SOCKS support rewritten] | |
23 | # | |
24 | # Notes: | |
25 | # | |
26 | # - shared libperl support is tricky. if ever libperl.a ends up | |
27 | # in /usr/local/lib/* it can override any subsequent builds of | |
28 | # that same perl release. to make sure you know where the shared | |
29 | # libperl.a is coming from do a 'dump -Hv perl' and check all the | |
30 | # library search paths in the loader header. | |
31 | # | |
32 | # it would be nice to warn the user if a libperl.a exists that is | |
33 | # going to override the current build, but that would be complex. | |
34 | # | |
35 | # better yet, a solid fix for this situation should be developed. | |
