it seems to assume sys/types.h and (funnily enough) errno.h, amongst others,
so it's mildly APE; many of the others are included only if many things are #defined
so might not matter.  the assumed library is essentially APE

system.h (644 lines) has many things like this:
	/* 1 if we have C99 designated initializers.  */
	#if !defined(HAVE_DESIGNATED_INITIALIZERS)
	#define HAVE_DESIGNATED_INITIALIZERS \
	  ((GCC_VERSION >= 2007) || (__STDC_VERSION__ >= 199901L))
	#endif

	/* 1 if we have _Bool.  */
	#ifndef HAVE__BOOL
	# define HAVE__BOOL \
	   ((GCC_VERSION >= 3000) || (__STDC_VERSION__ >= 199901L))
	#endif

	/* Test if something is a socket.  */
	#ifndef S_ISSOCK
	# ifdef S_IFSOCK
	#   define S_ISSOCK(m) (((m) & S_IFMT) == S_IFSOCK)
	# else
	#   define S_ISSOCK(m) 0
	# endif
	#endif

	/* Test if something is a FIFO.  */
	#ifndef S_ISFIFO
	# ifdef S_IFIFO
	#  define S_ISFIFO(m) (((m) & S_IFMT) == S_IFIFO)
	# else
	#  define S_ISFIFO(m) 0
	# endif
	#endif

but then i can't find them used.
