Re: head -r324071 system clang 5 based powerpc64 building ports: lang/gcc7 messed up by a matching name vec_step? [vec_step macro name in gcc7's altivec.h]

2017-09-29 Thread Mark Millard 
Summary of later additions:

devel/powerpc64-gcc has the same problem as gcc7
in this clang-based powerpc64.

My note about using gcc 4.2.1 for the kernel
build was wrong. (My 32-bit powerpc builds
are that way, not the powerpc64 ones.)
