[Bug c/14489] New: alternate keywords for visibility attribute

["markus+gcc at gyger dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The Sun ONE Studio 8 and Sun Studio 9 compilers on Solaris support the linker
scoping specifiers __global, __hidden and __symbolic which roughly correspond to
gcc's default, hidden and protected visibility attributes. Is there a chance to
have these keywords supported on gcc?  E.g.

__global   void linker_scope_global()   {}
__hidden   void linker_scope_hidden()   {}
__symbolic void linker_scope_symbolic() {}
           void linker_scope_default()  {}

in addition to

__attribute__ ((visibility ("default")))   void linker_scope_global()   {}
__attribute__ ((visibility ("internal")))  void linker_scope_internal() {}
__attribute__ ((visibility ("hidden")))    void linker_scope_hidden()   {}
__attribute__ ((visibility ("protected"))) void linker_scope_symbolic() {}
                                           void linker_scope_default()  {}

The command line option -xldscope={global|hidden|symbolic} allows to set the
default scope. See also:
