[boost] 1.30.0->1.30.2: no more thread support for Linux?

boost-1.30.2, SuSE Linux 8.2, GCC-3.3:

an #include <boost/thread.hpp> results in 
        #error Thread support not available!

It seems that since 1.30.2 on Linux it is
disabled by default, correct? why? 

gcc.hpp reads:

#if [...] !defined(linux) && !define(__linux) && !define(__linux__)
# define BOOST_HAS_THREADS
#endif

so...how do I enable threads for Linux?

TIA,
Geurt
