patch file

just report back here, I've tried following patch (which is already in upstream's gcc-4.8 branch). and compile eigen-3.2.0 with USE=doc, just fine.

Thanks for tackling down this.;a=commit;h=2504715442db6134015d01fa1f8bf20f194da476

(share the patch here if anyone willing to test, with following commands)
$ mkdir -p /etc/portage/patches/sys-devel/gcc-4.8.2/
$ cp 01-gcc-4.8-stl_algo.patch /etc/portage/patches/sys-devel/gcc-4.8.2/
Comment 3 Ryan Hill (RETIRED) gentoo-dev 2013-12-23 21:36:06 UTC
Fixed in 4.8.2 p1.1.  USE flag changes will trigger a rebuild for everyone.
