dnl Tests whether the compiler supports the command-line option

dnl __attribute__((__visibility__("hidden"))) and

dnl __attribute__((__visibility__("default"))).
|

dnl Does *not* test for __visibility__("protected") - which has tricky

dnl semantics (see the 'vismain' test in glibc) and does not exist e.g. on

dnl MacOS X.
|

dnl Does *not* test for __visibility__("internal") - which has processor

dnl dependent semantics.
|

dnl Does *not* test for #pragma GCC visibility push(hidden) - which is
|

dnl "really only recommended for legacy code".
|

dnl Set the variable CFLAGS_VISIBILITY.

dnl Defines and sets the variable HAVE_VISIBILITY.
