Merge of r4004, r4005: Solaris related fixes: *) Detect POSIX semaphores in librt on Solaris (ticket #3). Patch by Denis Ivanov. *) Lower optimization level for Sun Studio before 12.1. At least Sun Studio 12 has problems with bit-fields exposed by nginx code (caught by test suite). They seems to be fixed in Sun Studio 12.1. As a workaround use "-fast -xalias_level=any" for older versions, it resolves the problem.
