Ricardo also sent me the source code for which he experienced this
problem.
It turns out that the bug is in inc2h.pl. There are a few hard coded items
in inc2h.pl that don't apply to some of the processors. Specifically, the
sfr aliasing to banks 2 and 3 for a processor with only banks 0 and 1
(e.g. a 16f84).
Kevin, how hard would it be to modify inc2h.pl to also parse the Microchip
.lkr files.
What I'm thinking is that we change the invokation of inc2h.pl to be:
inc2h.pl PROCESSOR_NAME [optional path to parent of header/ and lkr/]
Then inc2h.pl can build the .lkr and .inc file names and read the files.
The .lkr files have all of the information that resides in the data
section of inc2h.pl.

A short term work around is to target only the 16f877.
