That site seems to have been dead since last weekend. I'm working on an
updated version (with BAJ's help).

I think it's because there is only one version of crt0i.o shared by all
the 18F devices. It's not a problem because there isn't anything
"device specific" in the start up code anyway. While it is annoying it
can be ignored. You could always modify the make file for crt0i.o to
compile it with -ppic18f252 then the warning would go away (I think).
I've worked out what I think is a better build process for sdcc that
installs everything properly. Can you can try it out for me ? I've used
it on a couple of my machines so far and it's worked fine. I think the
comments in David's HowTo about manually moving some files at the end
are now wrong because it seems the make files have been improved to do
it all automatically now. BUT I've not tested all the libs yet.
./configure --disable-mcs51-port --disable-gbz80-port --disable-z80-port
--disable-avr-port --disable-ds390-port --disable-ds400-port
--disable-hc08-port --disable-xa51-port
make
su -c "make install"
cd device/lib/pic16/
./configure
make
make lib-io
cd ..
make model-pic16
su -c "make install"
