This commit fixes bug 1840. The problem is that the palm support declared
a variable inside of a case statement. When I integrated the patch for palm support I streamlined the switch. This lost the brackets that would be required to declare vars inside of switch statements. The bug slipped by because I wasn't doing arm compiles at the time. Sorry. This patch fixes it. It also slides in some corrections associated to what open and sscanf return. It should not cause any behavior change. Thanks goes to GoXbox Live for reporting the problem.
