What I show above may be almost enough to get the compile working
"right", if you add "-I-" to CFLAGS.  man gcc.  I just tested that,
and it didn't blow up.

I'd at least recommend that up in the Makefile where it says
# If you have a "pristine" source directory, point BB_SRC_DIR to it.
add lines that say "experimental and incomplete; tell the mailing
list <busybox@busybox.net> if you do or don't like it
so far."

P.S. I like the comments Erik added in busybox.h just ahead of
#define PROTOTYPES
#include "applets.h"
#undef PROTOTYPES
