Seeing the same on Fedora 34 on the v0.1.1 tag and on master. Reproduce with:

docker run --rm=true -it fedora:34 /bin/bash
# Inside docker image
dnf install -y gcc-c++ git cmake
git clone https://github.com/skystrife/cpptoml.git
cmake -B cpptoml-build -S cpptoml
cmake --build cpptoml-build

Adding #include <limits> too include/cpptoml.h fixes the issue, as addressed in #123

Can confirm, GCC 9.4.0 against C++17. In my codebase I just include <limits> before including <cpptoml.h>

#include <limits>
#include <cpptoml.h>
