Right, the reason why it only adds the "s" flag on win32 is because boost
libs only have that flag on win32 for their static libraries. The reason is
that on linux the static boost libs still link against the shared c
runtime, while on windows they link against the static c runtime. So the
variable controls wether to link against a shared or a static boost lib,
which means lib<component>-<compiler>-<threading>-<version>.a on linux and
similar on windows, except that here the "s" flag is needed.
All this based on a normal boost installation from source, not using the
experimental cmake buildsystem. If that one does it differently thats a bug
in the cmake buildsystem for boost.
