[Boost-users] [test] How to ignore a signal?

I've a test case which receives the SIGCHLD signal on Solaris. Boost.Test catches it and prints an error message although in that test case SIGCHLD s perfectly fine. How do I make Boost.Test ignore this signal? I found BOOST_NO_SIGNAL_HANDLING back in Boost.Test 1.33.1 but it doesn't seem to exist anymore in 1.36.0? Boris
