I've posted this to bugzilla but no one's really responded. There was
one response but it did not help. Please help.

As near as I can tell, gcc should build with visibility support iff
    you are using gnu ld.

Since you are running linux, I can't imagine you might be using
    anything else. So I suspect a bug somewheres. When you file a bug
    report, you should include the output of ld --version, gcc
    --version, and uname -a, in addition to the info requested at
    gcc.gnu.org/bugs.html .

I suppose you could reconfigure and rebuild gcc, adding --with-gnu-ld
    to your configure arguments, but it seems a bug that that should
    be necessary on a platform where SFAIK only gnu ld is available.

Yeah It's stock fsf gcc. The distro I use is Sourcemage and it downloads
from gcc directly from the gnu site (and it's md5 verified).  The thing
is this has only happened to a few people and not the rest, we don't
know why.

First, make sure you are using fsf gcc 3.3.3 and not the derivative
shipped by your distro maker (it seems all distros hand-roll their own
gcc derivative ... don't ask me why.)
If you can still reproduce with fsf gcc, I think you should report
this as a bug. There's a similar bug 
reported against 3.4-branch: 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13134
but it doesn't mention 3.3.3 .

visibility attribute not supported?!

[Jeremy Kolb]

I'm running linux 2.6.3, gcc 3.3.3 on an amd t-bird.  When I try to
compile glibc I get a warning about the visibility attribute not being
supported. I've tested this out with a test program that uses the
visibility attribute and that fails as well.  So glibc won't build for
me.  How do I enable the visibility attribute? I've recompiled binutils
and gcc but I still get the same error.
