In a recent FreeBSD 14 buildbot build, I see the following compiler warnings:

Objects/mimalloc/prim/unix/prim.c:66:12: warning: unused function 'mi_prim_open' [-Wunused-function]
Objects/mimalloc/prim/unix/prim.c:69:16: warning: unused function 'mi_prim_read' [-Wunused-function]
Objects/mimalloc/prim/unix/prim.c:72:12: warning: unused function 'mi_prim_close' [-Wunused-function]
Objects/mimalloc/prim/unix/prim.c:75:12: warning: unused function 'mi_prim_access' [-Wunused-function]

I scheduled FreeBSD builds to see if the code still builds and if warnings are done.

With this change, build succeeded on the 3 FreeBSD buildbot jobs:

• https://buildbot.python.org/all/#/builders/1228/builds/69
• https://buildbot.python.org/all/#/builders/1255/builds/25
• https://buildbot.python.org/all/#/builders/1278/builds/7

Moreover, I don't see compiler warnings anymore about Objects/mimalloc/. So the change works as expected.

LGTM. Thanks.

@DinoV: how can you make these changes upstream? I would prefer to not lose them at the next mimalloc sync.

[vstinner]

Merged. Thanks @furkanonder for your fix.
