New Revision: 185445

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=185445
Log:
This patch mostly adds several test cases reduced from full-scale attempts to
use PPH.

  c?anonymous* -- problems handling anonymous/tagless types
  c?features* -- problems with benign macro redefinitions
  x?tmpldfltparm* -- inappropriately merging default template arguments

It also add an option -fpph-check to refine our check for headers compatible
with PPH.  It implies -fprimary-system-header-okay and checks for the main
source file missing a guard.  Generating a pph file implies the same check.

Tested on x64.
