Description Ryan Hill (RETIRED) gentoo-dev 2011-02-08 02:39:03 UTC 
zziplib uses LDFLAGS="--export-dynamic".  Linker flags starting with -- are actually silently ignored on linker command lines.  4.6 just doesn't accept them.  

See http://gcc.gnu.org/PR46410 or http://gcc.gnu.org/PR47390.

Given comments in those bugs, it seems that -export-all-symbols should be fixed too.
Comment 3 Ryan Hill (RETIRED) gentoo-dev 2011-02-08 03:27:22 UTC 
are you talking about in zziplib or gcc?
Comment 4 SpanKY gentoo-dev 2011-02-10 02:21:40 UTC 
i tweaked the patch to apply against configure (since we're avoiding running autotools atm) and added to the tree.  cheers !

Actually this bug makes the linking of zziplib fail on prefix/darwin/macos/10.5/x64, with gcc-4.2.1.
