I'm sure you know this already, but just in case..
in math.c the following line appears:
short long e[23] = {2097152, 1238021, 654136, 332050, 166669, 83416, 41718, 20860, 10430, 5215, 2607, 1304, 652, 326, 163, 81, 41, 20, 10, 5, 2, 1, 1};
(well,in MPLAB it was one line)

MPLAB replies with the following error:

Error - symbol 'e' has multiple definitions.
