I've revisited the issue of missing socket timeouts on Solaris and noticed that they actually exist in OpenSolaris since integration of the Volo framework in fall 2008 - but the autoconf tests failed due to missing libs like in this case:
configure:28453: checking whether SO_RCVTIMEO works configure:28496: gcc -o conftest -m64 -D_REENTRANT -pthreads conftest.c >&5 Undefined first referenced symbol in file socket /var/tmp//ccXeai7q.o setsockopt /var/tmp//ccXeai7q.o Nils
