The "-float" option on cc has never affected default promotion to
double in function arguments.  It only affects intermediate results in
floating point calculations. The cc man page in IRIX 3.3.1 explicitly says
this ("This option does not affect float function arguments, which are
always promoted to double unless function prototypes are used."), but
earlier versions (3.2) did not.
