Fix warning in setjmp/jmpbug.c.
This patch fixes a "set but not used" warning in setjmp/jmpbug.c. A variable is used only to store the result of alloca. A cast to void is added to avoid the warning, and the variable is made volatile to ensure the call to alloca isn't optimized away for being unused. Tested for x86_64. * setjmp/jmpbug.c (test): Make foo volatile and cast it to void.
