svn commit: r401707 - head/graphics/alembic/files

[Alexey Dokuchaev]

Author: danfe
Date: Sun Nov 15 14:36:48 2015
New Revision: 401707
URL: https://svnweb.freebsd.org/changeset/ports/401707

Log:
  Unbreak the build on PowerPC, in a simple way: replace deprecated __sync_*
  function with corresponding __atomic_* counterpart and link with libatomic
  against GCC.  This should be no-op on Tier-1 architectures (against Clang),
  since that code branch is guarded by __GNUC__ >= 4 && __GNUC_MINOR__ >= 4.

Added:

  head/graphics/alembic/files/patch-lib_Alembic_AbcCoreOgawa_StreamManager.cpp   (contents, props changed)
