Hi,

I am referring NetBSD-v1.6
In files like vfprintf.c, vfscanf.c and vprintf.c
of the source directory lib/libc/stdio, i noticed that
the macro _BSD_VA_LIST_ is used instead of the type va_list.

I noticed that stdarg.h defines the type va_list, it doesnot 
define a type _BSD_VA_LIST_. 

Is there a reason to use _BSD_VA_LIST_?
When these files are compiled for ARM or PPC architecture,
then respective compiler stdarg.h should be referred to 
compile the above files?

Thanks in advance
