Hi Pierrick
This works for me on Alma 9.2 and Debian 12
```
# CONFIG_SITE.Common.linuxCommon
# ...
CODE_CPPFLAGS += -fno-strict-aliasing
USR_CXXFLAGS += $(STD_CXXFLAGS)
STD_CXXFLAGS = -std=c++20
```

I'd like to build our EPICS software (starting on an Alma Linux 9 platform) for C++17 or even C++20. I'm presently building with C++11 by adding -std=c++11 to the USR_CXXFLAGS in configure/CONFIG_COMMON. However, when I tried c++20/c++17/c++14 and it failed in every case with:
resourceLib. A colleague of mine played with the configure/CONFIG.gnuCommon and had a different level of success and failure. Any help, even pointing me to the correct documentation would be greatly appreciated.
