GCC hidden visibility closely mimics the Windows DLL import/export feature, which cleans up the symbol export table and leads to faster startup times as well as a more stable ABI. This PR has no immediate effect until GCC is instructed to hide symbols with -fvisibility=hidden -fvisibility-inlines-hidden. I did not enable this yet because unlike MSVC, GCC does not export type info and vtables by default, so this PR depends on eProsima#88 to work. Signed-off-by: Timo Röhling <[email protected]>
