Looks good.

Looking at
   $ git grep -P 'IUSE.*[" ]cxx' # (full output) http://dpaste.com/1D0RC27.txt
notable changes are:
  dev-libs/boehm-gc/boehm-gc-8.0.4.ebuild:IUSE="cxx static-libs +threads"
  dev-libs/gmp/gmp-6.2.0.ebuild:IUSE="+asm doc cxx pic static-libs"
  sys-libs/db/db-18.1.32.ebuild:IUSE="doc java cxx tcl test"
and maybe
  app-text/poppler/poppler-0.86.1.ebuild:IUSE="cairo cjk curl cxx debug doc +introspection +jpeg +jpeg2k +lcms nss png qt5 tiff +utils"
