[Rd] changes in src/unix/system.c break builds on FreeBSD

[Rainer Hurling]

Dear R devs,

For some days now (~ February, 4th), I am not able to build the recent
tarballs of R-devel on a FreeBSD test box anymore. The breakage seems to
be related to the newest overhaul of src/unix/system.c:


[..snip..]

Stop.

Perhaps someone can give me a hint, want to do next?

Please let me know, if I should provide more information or can test
something.

Many thanks in advance,
