There is no RLIMIT_NPROC limit in Solaris. This causes compilation of

src/remote/inet_server.cpp

 to fail. It could be fixed by checking if RLIMIT_NPROC is defined as follows:

#if defined(UNIX) && defined(HAVE_SETRLIMIT) && defined(HAVE_GETRLIMIT) && defined(RLIMIT_NPROC)
raiseLimit(RLIMIT_NPROC);
