format doesnt use regex, nor shared_ptr, and I suppose it's not the only
lib using std iostreams, though it seems format and ios_state are the
only libs suffering from this unwanted pthread linking problem.

ios_state and format share some similarities : they both are linked
statically (for the same reason : metrowerks needs to link statically
when using <locale>), use some streams, and use boost_test_exec_monitor.

Could this be a bad combination ?

hmm, I'd prefer not link for multi-thread for every compilers just to
work around this problem. (format is probably not thread-safe, so
compiling it with <threads>multi might induce people in error)

Is it possible to supply different build requirements for different
toolsets ?
if so, I'd like to make format tests link dynamically (except for
metrowerks), and see if this gets rid of the problem with intel-7.1 .
