Chip Salzenberg sent me a complete patch to add System V IPC (msg, sem and shm calls), so I added them. If that bothers you, you can always undefine them in config.sh. :-)
About this quote
- What does it mean?
- Wall notes that he added System V IPC calls via a patch, but they can be disabled if unwanted.
- In plain terms
- He added message, semaphore, and shared‑memory support, which you can turn off.
- What can you take from it?
- You can customize Perl’s features by undefining them in config.sh.

Putting it to work
Questions to consider
- When should you strip optional features from a language?
- What are the trade‑offs of a minimal build?
Another view
Disabling features may break scripts that rely on them.
