+/*
+ *	gcc-1.32 (sun4-os4) has a problem passing structure arguments.
+ *
+ *	If the type FLT is changed to float, all problems disappear.
+ *
+ *	If PRINTF is defined and -O is *not* used, the program terminates
+ *	with a segmentation fault.  In all other cases I've tried, the
+ *	program runs, but the arguments to foo are not properly copied.  
+ *	To be precise, in foo, the value that one would normally expect
+ *	to find in b.y is overwritten with that of b.x. (see output in
+ *	comments below)
