| 3 | # This is a hints file for DGUX, which is EMC's Data General's Unix. It |
| 4 | # was originally developed with version 5.4.3.10 of the OS, and then was |
| 5 | # later updated running under version 4.11.2 (running on m88k hardware). |
| 6 | # The gross features should work with versions going back to 2.nil but |
| 7 | # some tweaking will probably be necessary. |
| 8 | # |
| 9 | # DGUX is an SVR4 derivative. It ships with gcc as the standard |
| 10 | # compiler. Since version 3.0 it has shipped with Perl 4.036 |
| 11 | # installed in /usr/bin, which is kind of neat. Be careful when you |
| 12 | # install that you don't overwrite the system version, though (by |
| 13 | # answering yes to the question about installing perl as /usr/bin/perl), |
| 14 | # as it would suck to try to get support if the vendor learned that you |
| 15 | # were physically replacing the system binaries. |

| 19 | # The standard system compiler is gcc, but invoking it as cc changes its |
| 20 | # behavior. I have to pick one name or the other so I can get the |
| 21 | # dynamic loading switches right (they vary depending on this). I'm |
| 22 | # picking gcc because there's no way to get at the optimization options |
| 23 | # and so on when you call it cc. |

| 94 | # that when a normal program tries to access one of these elinks it sees |
| 95 | # no such file (like stat()ting a mis-directed symlink). Setting |
| 96 | # $plibpth to explicitly include the place to which the elinks point |
| 97 | # allows Configure to find libraries which vary based on the development |
