New Revision: 408296
URL: https://svnweb.freebsd.org/changeset/ports/408296

Log:
  Fix the build on FreeBSD 9.x.  Somehow recent improvements in upstream
  GCC around detecting support for isinf and isnan only went half way.

Added:
  head/lang/gcc6-devel/files/patch-libstdc++-configure   (contents, props changed)

Added: head/lang/gcc6-devel/files/patch-libstdc++-configure
