And if the above is not enough, consider this: SunOS `sprintf' returns
a char*, not an int!  (They return a pointer to the first argument.)

At one point this caused me to walk through all the system
headers ``fixed'' by GCC on a Sun and correct these snafus (by
comparing the prototypes with the system man pages), so I could have
prototypes *and* write programs that don't crash.
