boost thread & get_nproc

[Lipp, Gerhard]

hello!

i am trying to get the boost.thread 1.43 lib running, using buildroot
with uclibc 0.9.31 configured.
when building bjam from within buildroot env, the compiler complains
about an undeclared get_nprocs function, which is ifdefed by _GNU_SOURCE
(file: boost/libs/thread/src/pthread/thread.cpp, method
boost::thread::hardware_concurrency).
afaik,  get_nprocs is not part of the libc standard and thus not
implemented in uclibc up to now. apparently one could implement
boost::thread::hardware_concurrency with means of sysinfo, but it seems
this isnt implemented either.
 
i would appreciate any help!
regards,
 
gerhard
