My first thought is the linker script might be the problem.

There is some differences between the 16F1947_g.lkr located in the MAPASM=20
Suite\LKR directory and that provided under MPLABX\MPASMx\LKR.

Namely the latter (dated 7/11/2013) has 7 code pages listed rather than =20
the 6 by the earlier file (dated 12/5/2011).

The MPLABX version has:

CODEPAGE   NAME=3Dpage0      START=3D0x0               END=3D0x7FF         =
       =20

The earlier file has

       =20
