Bug #7478: Do not include vararg.h - always include stdarg.h
https://bugs.ruby-lang.org/issues/7478#change-35287

Author: funny_falcon (Yura Sokolov)
Status: Feedback
Priority: Low
Assignee: 
Category: core
Target version: 1.9.3
ruby -v: ruby 1.9.3p327 (2012-11-10 revision 37606) [x86_64-linux]


Cause : https://gist.github.com/4172330

It seems that stdarg.h is included in many separate C files unconditionally:
array.c, class.c, error.c, sprintf.c, include/ruby/ruby.h, include/ruby/encoding.h - all includes stdarg.h without checking for HAVE_STDARG_PROTOTYPES

So that, why there is check in include/ruby/intern.h, vm_core.h, vsnprintf.c (and may be somewhere else)
