+templates and namespaces. For even more savings, combine with the

+@item -fvisibility=@var{default|internal|hidden|protected}
+@opindex fvisibility
+Set the default ELF image symbol visibility to the specified option - all
+symbols will be marked with this unless overrided within the code.
+Using this feature can very substantially improve linking and
+load times of shared object libraries, produce more optimised
+code, provide near-perfect API export and prevent symbol clashes.
+It is @strong{strongly} recommended that you use this in any shared objects
+you distribute.
+
+Despite the nomenclature, @code{default} always means public ie;
+available to be linked against from outside the shared object.
+@code{protected} and @code{internal} are pretty useless in real-world
+usage so the only other commonly used option will be @code{hidden}.
+The default if -fvisibility isn't specified is @code{default} ie; make every
+symbol public - this causes the same behaviour as previous versions of
+GCC.
+
+A good explanation of the benefits offered by ensuring ELF
+symbols have the correct visibility is given by ``How To Write
+Shared Libraries'' by Ulrich Drepper (which can be found at
+@w{@uref{http://people.redhat.com/~drepper/}}) - however a superior
+solution made possible by this option to marking things hidden when
+the default is public is to make the default hidden and mark things
+public. This is the norm with DLL's on Windows and with @option{-fvisibility=hidden}
+and @code{__attribute__ ((visibility("default")))} instead of
+@code{__declspec(dllexport)} you get almost identical semantics with
+identical syntax. This is a great boon to those working with
+cross-platform projects.
+
+For those adding visibility support to existing code, you may find
+@samp{#pragma GCC visibility} of use. This works by you enclosing
+the declarations you wish to set visibility for with (for example)
+@samp{#pragma GCC visibility push(hidden)} and
+@samp{#pragma GCC visibility pop}. These can be nested up to sixteen
+times. Bear in mind that symbol visibility should be viewed @strong{as
+part of the API interface contract} and thus all new code should
+always specify visibility when it is not the default ie; declarations
+only for use within the local DSO should @strong{always} be marked explicitly
+as hidden as so to avoid PLT indirection overheads - making this
+abundantly clear also aids readability and self-documentation of the code.
+Note that due to ISO C++ specification requirements, operator new and
+operator delete must always be of default visibility.
+
+An overview of these techniques, their benefits and how to use them
+is at @w{@uref{http://www.nedprod.com/programs/gccvisibility.html}}.
