--- Comment #3 from Dave Blanchard <dave at killthe dot net> --- gccreport-ada/scripts/install/stage1/cross/gcc is the file you want for the gcc cross compiler 'configure' options. You should be able to get a strong clue from the provided error that tells you what's happening. It's as if GNAT, only for that multilib, somehow gets a wrong idea about the size of Int64. I just don't understand Ada or GNAT well enough to take a stab at fixing it. I extensively tested this and confirmed that there is nothing special going on in the script which is somehow fucking up the build. It's 100% GNAT.
