4395	Intel 11.1 defines _GNU_SOURCE, breaking the get_nprocs test in thread.cpp	Robert Lupton <rhl@…>	Anthony Williams	"In a bug related to #2053, there's code in
`libs/thread/src/pthread/thread.cpp` that attempts to only call `get_nprocs` on gnu platforms that define _GNU_SOURCE (cf. http://lists.boost.org/Archives/boost/2010/05/166414.php)

Unfortunately, intel 11.1 appears to define _GNU_SOURCE, but not provide get_nprocs:
