Yes, that's annoying but normal. The libraries (especially the init-code 
in crt=.o) are compiled for the pic18f452 because the libraries only 
access pins/ports vailable in all PIC16s (the 452 is just small enough 
not to introduce ports other PICs don't have).
Actually, the warning is not emitted by SDCC -- its the linker (gputils' 
gplink) that emits it (gputils/gplink/gplink.c:61).

This message can be removed by explicitly specifying the linker script using
sdcc -Wl,"-s <SCRIPT_TO_USE>" [...]
when linking...
