            Bug ID: 65632
           Summary: gcc-4.8.4 fails to build native gcc for Gentoo/FreeBSD
                    using crosscompiler on Gentoo/Linux
           Product: gcc
           Version: 4.8.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dark_templar at hotbox dot ru

I'm using Gentoo/Linux to crosscompile base system for Gentoo/FreeBSD. In the
process I've hit two issues with gcc while building compiler for system with
already built crosscompiler. First one is that gcc tries to use malloc.h while
on FreeBSD it produces error using #error directive. Second one is that it
produces is caused by using unavailable *_unlocked functions.

I've made a workaround patch for problem one and found a patch for problem two.
