pgRouting 3.7.0 fails to compile under mingw64 gcc 13.2

[robe2]

I'm in the middle of switching my old mingw gcc 8.1 chain to my new mingw gcc 13.2 chain

Problem
While compiling and regressing works fine under my gcc 8.1 chain, it's failing at 59% of compile.
I've also tried pgRouting 3.6.2 and pgRouting 3.5.1, to rule out it was recent changes, and those fail as well.

This is compiling against PG17. I haven't tried yet compiling with other versions of PostgreSQL.

Here is the output

I added #include <cstdint> to include/cpp_common/Dmatrix.hpp as you suggested and that seems to have done the trick.
