Hello all
when we patch httpd.tproxy to httpd-2.2.14, and compile it, it returns some error such as prctl(), capset() undefined reference in freebsd.

os/unix/.libs/libos.a(unixd.o): In function `keep_capabilities':
/root/httpd-2.2.14/os/unix/unixd.c:82: undefined reference to `prctl'
os/unix/.libs/libos.a(unixd.o): In function `set_capabilities':
/root/httpd-2.2.14/os/unix/unixd.c:99: undefined reference to `capset'
*** Error code 1

Stop in /root/httpd-2.2.14.

these two functions are linux syscall that only implements on linux!
are any freebsd based of these functions?
how we can compile it without any error?
