https://bugzilla.mozilla.org/show_bug.cgi?id=273336#c0 describes the advantages of #pragma visibility over -fvisibility=hidden (at least on Linux; from bsmedberg's post it sounds like it doesn't make a difference on Mac). (That patch was later conditioned on configure tests in bugs 293438 and 307168 to work around compiler bugs; this is the configure test you're observing.) -David -- 𝄞 L.
