You did not explain your purpose in asking the question. Finally you have: > I'm trying to decide what recommendations to make with repect to > -fvisibility for a forthcoming O'Reilly C++ book. Thank you. Next time, please include your purpose the first time you ask the question. That way you'll get a good answer sooner. In the past, we've repeatedly gotten queries of this kind from people who really wanted to know whether a given option was supported on a *particular* platform. The problem with the question the way you phrased it is that it's hard to know the right answer. There are a relatively small number of platforms that get a lot of testing, but there are huge numbers of minority platforms out there for which the GNU toolchain sort-of works.
