I think for completeness.

Ok, I'm opening up the can of worms again.

See this: <http://mail.nongnu.org/archive/html/avr-libc-
and related thread.

There was agreement by Ted and Jörg (and no disagreement 
from Marek per se) about the patch in the above message 
which changes avr-gcc to have a 32 bit type in -mint8 and 
to drop the 64-bit type in -mint8. It seems that there is 
agreement that this makes more sense than the current setup.

I would rather get this patch in to GCC (Hello, Denis?) and 
keep the 32 bit pgmspace macros for -mint8. So, yes, I have 
some objections.

Oh, and btw, shouldn't -mint8 be documented somewhere in 
the GCC manual?
