Disable SO_SNDTIMEO and SO_RCVTIMEO on Solaris
Disable SO_SNDTIMEO and SO_RCVTIMEO on Solaris

setsockopt(SO_SNDTIMEO/SO_RCVTIMEO) returns -1 with errno == 99 (not supported)
I have temporarily disabled the code with #ifdef __sun, but should update
the configure script to test for this and set the correct macros.
