Which LT_INIT option would enable the hidden symbol visibility support?
The option -fvisibility=hidden is useful and supported by all major
compilers today including gcc, clang, and icc. There is
-xldscope=hidden on Solaris too. I was hoping to see something similar
to adding "-fPIC -DPIC" when appropriate using some option (if not by
default). I was hoping for something similar to "win32-dll" but for
sources that use__attribute__((visibility("default")).
