Subject: [Boost-build] gcc visibility support patch
From: Jürgen Hunold (juergen.hunold_at_[hidden])

Hi !

I've attached a patch to add support for gcc-4.x "visibility" to Boost.Build.
This will fix #2114.
It adds two new features, "visibility" and "visibility-inlines" which control
the corresponding gcc flags. This is necessary because these flags are othogonal
and control different behaviour. I've omitted -fvisibility-ms-compat because
this flags should not be used in new code and users can always specify those
using <cxxflags>. See for details.

Comments welcome, this is work in progress and just a "works for me" draft.
