[ruby-core:31652] recent configure gcc -fvisibility hides access to class variables in C extensions.

From: Rocky Bernstein <rockyb@...>
Date: 2010-08-08 13:44:29 UTC
List: ruby-core #31652
A change in SVN 28712
  Thu Jul 22 06:38:18 2010  Nobuyoshi Nakada  <[email protected]>

    * configure.in (XCFLAGS): use -fvisibility=hidden if possible.

has the effect, I believe, of hiding values like the class constants for
rb_cRubyVM and
rb_cISeq (RubyVM::InstructionSequence constant),  and thread pointer
ruby_current_thread if not others.

In each case there is a way to get these by more convoluted means from
inside a C extension. For example,  rb_cRubyVM
can be obtained, I think , by
    VALUE rb_cRubyVM = rb_const_get(rb_mKernel, rb_intern("RubyVM"));

Was it the intention to hide these particular C variables from extensions?
