Hi,
Your code compiles fine for a 12LF1552 using PBP 3.0.8.4 and MPASM 5.45.
I don't have 2.6C available to try with but it seems as if the warning is thrown by the assembler and not by the compiler. Googling a bit further suggests that the problem might be due to a corrupt or incompatiable .inc file for the device (that would be the .inc file in the MPASM folder, not in the PBP folder).
You didn't say which version of MPASM you're using but I'd try updating or re-installing MPLAB. I'm attaching the p12LF1552.inc file from my MPASM installation (renamed to .txt to able to upload it). You could try replacing yours with this one and see if it helps.
/Henrik.
