gcc-build-logs.tar.bz2

gcc-4.8.3 with gcj enabled fails to compile on musl.

I found these patches from alpine, they apply correctly but do *not* resolve the issue:

Comment 1 SpanKY gentoo-dev 2014-10-24 15:42:46 UTC 
there is no gcc-4.8.3-r99 in the tree

No, it's from the musl branch in the hardened-overlay, that's why I CC'd blueness.
Comment 3 SpanKY gentoo-dev 2014-10-24 16:17:42 UTC 
toolchain@ only handles ebuilds in the main tree.  overlays are handled by the respective overlay owners.

Those patches are not going to fix that error.  Re-sync and try emerging gcc-4.8.3 again.

Anthony,

it worked, thanks a lot for the patch! I'm trying to bootstrap a JDK on a musl system. Cross you finger I'm not running into any major bugs ;-)
