Description John F. Carr 2024-04-03 15:43:21 UTC

The newly introduced kenv() declaration in <unistd.h> causes compilation of plan9port to fail.  The function is not yet in any FreeBSD release, having been added in January, 2024.

Also reported upstream at https://github.com/9fans/plan9port/issues/648.
