Looking at the linker script, the 872 doesn't appear to have any udata
section.  Looks as if it needs udata_shr instead.  There was a discussion
about this just the other day with respect to some 12F chips.  I don't have
the appnote, was it specific to the 872?  A 0x38 long udata section will fit
in most 16F's, but apparently the 872 is an abberation.  Looking at the
linker script, you can't have any udata in that part.
