This patch simplifies the visibility compiler flag detection in configure and
makes it more generic to also support compilers other than gcc.
This simplification relies on the assumption that compilers support
-fvisibility=... if and only if they support
attribute(visibility("...")).
Hmm you're correct. I've naively assumed they both go hand in hand.
The latest Solaris Studio compilers support attribute(visibility), but
not -fvisibility. The absolute latest (12.4, released a few months back)
also support the clang has_attribute() extension for checking what's
supported (which is one of the reasons it's used in the X11/Xfuncproto.h
header in xproto 7.0.27 & later).
