[Bug middle-end/20297] #pragma GCC visibility isn't properly handled for builtin functions

["simon dot strandman at telia dot com" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #11 from simon dot strandman at telia dot com  2005-10-18 12:21 -------
I'm using gcc 4.0.2 with patches for gcc pr19664, pr20297 and pr19520. The
testcase from this bug passes without problems. Still firefox beta2 and current
CVS fails to build. I talked to the mozilla guys and they asked me to report it
here. Any ideas what might be wrong?

The 9999 version means that it's a CVS build in gentoo.

Binutils is version 2.16.1 and glibc is 2.3.5.
