Yes, `flock` is not part of POSIX[0]. However, I'm confused why exactly
FreeBSD
is having a problem with this, because as you can see from the FreeBSD
manual[1],
it's fully supported in FreeBSD with the inclusion of <sys/file.h>,
which is
indeed present. Maybe -D_BSD_SOURCE requires a specific version
provided, or
the definition order matters? Unfortunately I do not have a FreeBSD
system to
check this.

---blind errors---
src/stream.c:367:73: error: use of undeclared identifier
'MAP_ANONYMOUS'
image = mmap(0, 2 * lframe_size + lframe_size, PROT_READ |

The same is true here, see both:
http://pubs.opengroup.org/onlinepubs/9699919799/functions/mmap.html
https://www.unix.com/man-page/FreeBSD/2/mmap/
and note the lack / inclusion of support for MAP_ANONYMOUS respectively.
I'm sorry I cannot be of much more help. Good luck with this problem.
