Compiling with gcc visibility enabled

All, Recently I stumbled across a bug with building tdeaddons. The resolution was to change in my build script --enable-gcc-hidden- visibility to --disable-gcc-hidden-visibility. We have bug report 1285 to address the problem of compiling with hidden symbol support but no work has proceeded with that report. Currently we have no dependable list of which packages to build with gcc visibility enabled. What is the safe/sane policy for our build scripts? Darrell
