Re: Why are dwarf2 symbols getting assigned hidden visibility?

Thanks Ian.

I think at least one my issues is the wrong libgcc_s file is getting linked. It appears the new gcc 4.6 is linking to the NetBSD's system provided libgcc_s which is from version 4.1 Some symbols such as _Unwind_GetIPInfo info aren't there.

It may be that the package has an error in it and should be built statically anyway, but this seems to be a general issue. If the system libgcc_s is old, yet it's not allowed to replace it with a new version, what's the best way to deal with that? Would updating the spec definitions help the newly built gcc pick up the new libgcc_s?

/usr/lib/libgcc_s.so (NetBSD 5.1)
/usr/pkg/lib/libgcc_s.so (pkgsrc version)

Dealing with multiple versions of libgcc_s seems painful....
