New Revision: 329163
URL: https://svnweb.freebsd.org/changeset/base/329163

Log:
  Use standard pattern for stdargs.h
  
  We don't support older compilers. Most of the code in these files is
  for pre-3.0 gcc, which is at least 15 years obsolete. Move to using
  phk's sys/_stdargs.h for all these platforms.
