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..]

Perhaps someone can give me a hint, want to do next?
Let us know (which you have). This appears to be a lack of POSIX compliance on FreeBSD (even POSIX 2004, the current link being http://pubs.opengroup.org/onlinepubs/9699919799/functions/getrlimit.html), so was unexpected and you ought to file a FreeBSD bug report.
I think this FreeBSD bug report already covers the issue of partial non-compliance with the POSIX standard in question: <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=209729>.
I'll add a workaround in R-devel in r72147: let us know if that does not suffice.
Please let me know, if I should provide more information or can test something. Many thanks in advance, Rainer Hurling
