New Revision: 518121
URL: https://svnweb.freebsd.org/changeset/ports/518121

Log:
  Forward port r509607 | gerald | 2019-08-22 from lang/gcc8 since this has
  not been addressed upstream yet:
  
    clang on rs6000/powerpc* unfortunately poisons user namespace by default
    (without any special options or include files being required).
  
    Until that changes (or GCC changes) we need to avoid using vec_step as a
    variable name.
