devel/skalibs: fix build failure on DragonFly#1546
Merged
Conversation
> Generated by the DragonFly agentic build-fix loop and verified in a clean dev-env. Reviewed and accepted by operator `operator` before submission.
## Problem
The build failed on `@2026Q2` — classified `compile-error`, confidence `high`.
DragonFly's `<sys/event.h>` uses the BSD legacy types `u_short` and `u_int`, which are not visible when the compiler is invoked with `-D_POSIX_C_SOURCE=200809L -D_XOPEN_SOURCE=700`. The port does not define `__BSD_VISIBLE` or include `<sys/types.h>` with the appropriate visibility macros before including `<sys/event.h>`, causing the types to be unknown.
**Evidence:**
- From the build log (both bundles):
```
In file included from src/include/skalibs/keventbridge.h:11,
from src/libplaynice/keventbridge_end.c:10:
/usr/include/sys/event.h:67:2: error: unknown type name 'u_short'
u_short flags;
^~~~~~~
/usr/include/sys/event.h:68:2: error: unknown type name 'u_int'
u_int fflags;
^~~~~
```
- The compiler command shows `-D_POSIX_C_SOURCE=200809L -D_XOPEN_SOURCE=700`, which hides BSD extensions on DragonFly unless `__BSD_VISIBLE` is explicitly defined.
## Fix
Automated fix for the build failure in `devel/skalibs`.
## What changed
1 file changed, +6/-0

## Verification
Built successfully in a DragonFly dev-env (dsynth) for target `@2026Q2`.
