To be honest, I haven't noticed it.  You have to tell MPLAB that you are
using a 16f630/676 (Configure --> Select Device) but MPLAB seems to be
ignoring the 'list' directive in my source when I'm using the ICD2.

However, even if this comes up, change your source to use the 16f630/676
for debugging, then change to the proper part (12f629/675) before compiling
the final version into for burning into the chip.  You have to recompile
anyways because you don't want the ICD2 debug code in your final product.

I normally have sections of code enabled or disabled based upon whether or
not my debug line is commented out or not:

;  define emulate               ;un-comment this line while using emulator

   ifdef emulate
     LIST P=16F676,F=INHX8M,R=HEX
   else
     LIST P=16F675,F=INHX8M,R=HEX
   endif

PS - I'm used to faking out the tools while developing code for a target
processor for which I don't have the proper emulator pod.  This is just an
extension of that practice.
