The following test cases now fail on i686-apple-darwin10...

FAIL: gcc.c-torture/execute/builtins/sprintf.c compilation,  -O0                
FAIL: gcc.c-torture/execute/builtins/sprintf.c compilation,  -O1                
FAIL: gcc.c-torture/execute/builtins/sprintf.c compilation,  -O2

fomit-frame-pointer                                                             
FAIL: gcc.c-torture/execute/builtins/sprintf.c compilation,  -O3 -g            
                                                                   FAIL:
gcc.c-torture/execute/builtins/sprintf.c compilation,  -Os    

Mike Stump says this is because the call to  sprintf is unportable code. The
library is free to define sprintf and when it does this can fail. He suggest we
use...

int
(sprintf) (char *buf, const char *fmt, ...)

instead of the current...

int
sprintf (char *buf, const char *fmt, ...)

I can confirm that this change to
gcc/testsuite/gcc.c-torture/execute/builtins/lib/sprintf.c eliminates the
compilation failure under i686-apple-darwin10.
