On Linux the visibility of symbols marked with FL_EXPORT is always set to "default".
I can only change this if I edit Fl_Export.H and add "-fvisibility=hidden" to the build flags.
Why would I want to hide _all_ symbols? I was trying something out by building a library that's statically linked against FLTK and dynamically loaded, so I only wanted _my_ symbols to be visible.
Would be nice if there was an option in the build settings or if I could at least override the macros in Fl_Export.H with some CPPFLAGS (well I guess I could use -DFl_Export_H -DFL_EXPORT -fvisibility=hidden, but an easier way would be appreciated).
