When porting John Gilmore's PD tar to MINIX, I discovered an incompatibility
between MINIX's C compiler and others.  The code contained numerous 
constructs of this form:
	struct stat statbuf[1];
	...
	size = statbuf->st_size;
The MINIX C compiler objects violently, saying "error: -> applied to array".
Aztec C gives warnings but creates correct code output.  UNIX C compilers
obviously see nothing wrong with this, and my reading of K&R is that there
is nothing wrong with this construct -- whenever array names appear they
are converted to pointers, and -> is a valid operation on a pointer to a
structure.
