Description RJVB 2020-04-26 09:51:36 UTC 
In case (if not hope...) someone gets to this before me:

It would be useful to add -Wundef to the default compiler arguments used by the parser. Apparently this flag is not included in -Wall, and its absence leads to compiling warnings like

foo.c:N:5: warning: 'KCONFIG_VERSION' is not defined, evaluates to 0 [-Wundef]

which you just have to spot and which won't have any runtime repercussions if you're developing on a system where the version check is supposed to fail even if the version macro *is* defined.

I'm aware that you can also deduce the fact if a macro is defined from its colour when using the default code colour palette, but that is just about as easy as spotting the warning in a pile of compiler output.

(of course you can also wonder why KF5 framework headers don't include their version header like Qt headers do...)
