Hi,

recently I found a bogus semicolon an if statement. So I was searching for 
other possible problems with following command:

find linux-2.6.4-rc2 -name "*.c" -exec grep -Hn "\<if[[:space:]]*(\([^()]\|
([^()]*)\)*)[[:space:]]*;" {} \;

That found following possible problems:

linux-2.6.4-rc2/arch/um/kernel/tt/tracer.c:257:		if(WIFEXITED(status)) ;
linux-2.6.4-rc2/arch/i386/kernel/io_apic.c:2200:				if (check_nmi_watchdog() < 
0);

0);

linux-2.6.4-rc2/drivers/scsi/sg.c:514:	if (ppos != &filp->f_pos) ;	/* FIXME: 
Hmm.  Seek to the right place, or fail?  */

Best regards

P.S.: Wouldn't it be nice if gcc complained about these mistakes?
