statement that could be followed by ';' anywhere. However, with the goto
there, my compiler complains every time it's used:
"ball.c", line 402: warning: statement not reached
"ball.c", line 434: warning: statement not reached
"ball.c", line 442: warning: statement not reached
"ball.c", line 449: warning: statement not reached
"ball.c", line 452: warning: statement not reached
"ball.c", line 457: warning: statement not reached
"ball.c", line 479: warning: statement not reached
"ball.c", line 498: warning: statement not reached
None of the current uses care about an excess statement, but is there a
way to satisfy both desires?
