[Tinyos-8051wg] [Tinyos-2.0wg] Bug in nesC 1.2alpha10

[Joe Polastre]

I believe there is a bug in the new nesC with passing strings into a component.

I think that if you pass in a string and the string is used in
"uniqueCount", nesC is evaluating uniqueCount at the time that file is
processed rather than waiting until the full program is processed and
then assigning uniqueCount values.

To see the bug, compile apps/TestSPI for telosb.  You will get the
"comparison is always false due to limited range of data type" even
though the uniqueCount value should equal 2!
