So I have a FreeBSD port for got 0.39.  See the end of this message
for a list of patches, additional library functions, and interposed
header files.

Some of this is unavoidable, e.g. FreeBSD has no bsd.regress.mk.
There are various odds and ends, but apart from OpenBSD-specific
APIs the principal issues are...

Code:
* FreeBSD deviates from POSIX and has open(symlink, NO_FOLLOW)
  return EMLINK instead of ELOOP.
* Mismatches around int64_t, time_t, and format strings.

Shell scripts (regress/cmdline):
* OpenBSD followed GNU sed(1) and introduced -i with an optional
  argument.  FreeBSD added -i with a mandatory argument.  There
  is no way to specify an empty suffix that satisfies both
  syntaxes.
* mktemp(1) is non-standard, and despite FreeBSD having copied it
  from OpenBSD, they are now somewhat incompatible.

Except for test_log_in_worktree_different_repo, all regression tests
succeed.  This may be a related bug:

$ got co got.git
got: realpath: /home/naddy/got: No such file or directory

(An explicit "got co got.git got" works fine.)

Anyway, I'll import this into the FreeBSD ports tree soon.
