It seems that it doesn't build with releases of GCC from April 2025 onward, at least with default settings, because it doesn't build with the C23/C++23 standards.

Maybe such changes are more substantial than the typical differences between GCC releases?

Surely if that's all they would just build with an explicit -std=whatever setting?

Looking at the build log in the linked Debian issue, there is an argument setting -std=c++11. It seems as though an implicit inclusion of <cstdint> had been provided by libstdc++ in the past and was removed as of GCC 15.

Looks like they did in fact add the header detail to the porting guide:

Just closing some tabs and followed this trail a bit further, it looks like guix fixed the issue too:

it would be nice if g++ had an --implicit-includes=[foo,bar] option that would make it easier for a distro to shotgun fix such incompatibilities with CXXFLAGS rather than doing real work.

Isn't the --include option basically that?

That seems like kicking the can down the road in a way that's worse in the long run IMHO

I recently custom-built Guile for my Arch system, and found that it won't build with GCC 15, but will with 14, which is the only other version in the Arch repository. I think that the Guile maintainers will need to get busy fixing the incompatibilities in question, before GCC 16 appears.
