[zeromq-dev] [PATCH] DSO symbol visibility

[Martin Lucina]

Hi,

ok, so this seems to have broken the clang build. I'm guessing this is
because I test for -fvisibility support in configure.in with *any*
compiler, which succeeds, but the code which sets default visibility in
zmq.h/zmq.cpp is tied to checking for __GNUC__ >= 4.

Martin, can you please apply the attached patch? It's just a small change
to only try -fvisibility if we're actually using real G++ (or something
that claims to be compatible). It should fix the clang issue.
