What steps will reproduce the problem?
1. After the fix of issue #392 I updated the svn repo
2. from a clean objdir run configure and make
3. wait for the compilation to fail

What is the expected output? What do you see instead?

go1: warning: internal and protected visibility attributes not supported in
this configuration; ignored

Please provide any additional information below.

Tell me if you need the output of make and/or of configure. I get a good
number of warning during the build.

oops, I meant issue #329, not issue #392 which is unrelated.

Comment 3:

This error is coming from the .go_export section.  The gccgo import/export machinery 
will need an overhaul for Mac OS.  I don't know who will do that.

Status changed to LongTerm.

Comment 9:

This issue is about gccgo, not 6g.  Comment #8 is about 6g.  You should open a new issue
for 6g.

I like the way you think, but it doesn't work on any more recent release of Darwin either. I changed the title.

Following along as I'd love to have a go with gccgo on Darwin... :-)

@ianlancetaylor I see. That’s upsetting, but what to do.

P. S. Since the old Go which is bootstrappable from C is x86-only, and there are no binaries for ppc, we cannot get Go on Darwin PPC in a conventional way. Perhaps the old Go is fixable, but when I reviewed the source code last time it appeared non-trivial: it was not clear which values should be set for a number of arch-specific defines.
