>Description:


the visibility attribute is definitively broken in Solaris's gcc >=4
either in 32 or in 64 bit mode.
Suppress the usage of visibility_hiding in all package for solaris.


>How-To-Repeat:


bmake 
all package with visibility_hiding


>Fix:


kind (imlib2 example) of patch is:

[root@redhot 1058] diff -u src/lib/common.h.orig src/lib/common.h

-------------------------------------------------
look also at Xfuncproto.h
the package x11/libXft is broken because of this header in 32bit mode.

 I found this:  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46713
 which suggests it is still an issue.

 Perhaps this could be fixed in the wrappers rather than patching every package?

Blah.
Yeah, fixing it in the wrappers sounds like a good plan.
