Ah, ok, now I see.  I am configuring with --disable-lto for some reasons 
like http://sourceware.org/PR12742

I'd propose to move over to address@hidden and ask for a solution there 
(please CC me then).  Named addresses are new in GCC and AVR is the only 
target that makes extensive use of the new feature.

avr.c uses c_addr_space_name to get the names of address spaces for 
diagnostics, and likely it's a flaw in GCC's build machinery that does 
not arrange for that.
