--- Comment #8 from Søren Jæger Hansen <sjh at schilling dot dk> --- I get all this, and thanks for quick processing. Still I think it's a bit odd that -std=c++* and -std?=gnu++* gives different results, but I assume there's a good reason for that. We'll be using -std=gnu++23 for now and move to 64 bit later as a solution for us.
