Richard Guenther <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Target Milestone|--- |4.8.0 --- Comment #1 from Richard Guenther <rguenth at gcc dot gnu.org> 2012-09-24 13:54:07 UTC --- ISTR it worked for me when checking in -Og support with BOOT_CFLAGS/BOOT_CXXFLAGS="-Og -g". I don't have a host compiler with -Og support around, but I wonder how -Og can make a difference for preprocessing? Is it some configure tests giving different results?
