You really need to get in the habit of attaching the source that caused
the error.

I am going to guess that this is the problem...
There are no unprotected sections of DATABANK on the 16f870. So if you
create a udata section the linker has no place to put it. That is why
the error message says "type of section". The 16f877 has udata sections
so your code works on it.
You can either:
1. Switch to udata_shr sections.
2. Add the -r or --use-shared switch on the linker. That will allow
the linker to use the shared memory for udata or idata sections.
