Author: imp Date: Mon Feb 12 14:48:05 2018 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.
