I'm building LLVM - master branch - on a SLES15 SP1 machine, with Python 3.13.2 built from source (otherwise the build can't happen). The GCC version is 7.4.1.
CMake configuration is:
```
cmake -G "Unix Makefiles" -DLLVM_ENABLE_PROJECTS=clang -B build2 -S llvm -DCMAKE_BUILD_TYPE=Release -DPython3_EXECUTABLE=`which python3`
```
during the build of APFloat.cpp, I get the following errors:
```
