Microchip publishes a lot of crappy code.  They make great chips, but aren't
real good at programming them.

I don't know anything about this code, but I'm guessing it was written for a
chip with a single UART and you are trying to build it for a chip with two
UARTs.  That will require some manual editing.

I just dealt with this single/multiple UARTs issue myself, and have updated
my PIC development environment to deal with it in a nice way.  I plan on
releasing the updated version soon, after I've had more chance to test my
own code with it and run some regression tests.

In a nutshell, I've created a UART_SELECT macro that makes sure symbols
exist for the selected UART as if there was only one UART.  It also provides
wrapper symbols and string substitution macros for where the various
interrupt bits live.  For example, after doing UART_SELECT 1, RCREG will
refer to RCREG1, after UART_SELECT 2, RCREG will refer to RCREG2, etc.
