No, please, O_APPEND both in 4.2BSD and System III/V.  The various flavors
of UNIX differ in too many ways already; let's be grateful that there's one
extension which was done the same way in more than one variant...
(<fcntl.h>, which is what you're supposed to include, defines O_APPEND;
<sys/file.h>, which you're not supposed to include unless you're rummaging
through the kernel's file descriptor table, defines FAPPEND.  On 4.2BSD they
reference one another, so you get both with either include.)
