Does the @number() attribute work across multiple layers? I would think that it
should be able to, but perhaps I'm not using it correctly. I realize that the
test case below wouldn't do anything at run time, but I believe the syntax is
still correct. I get the error:
It should. If it doesn't, it's a bug... I'll look into it.

In component `NumberC':
NumberC.nc:5: parameter 1 must be a numerical type
TestNumberC.nc:
configuration TestNumberC {}
implementation {
components new NumberC(uint8_t);

NumberC.nc:
