C/C++ plugin: False error markers "Unable to resolve identifier" with GNU-C99 __flash qualifier

[gitdode]

I'm using the C/C++ plugin (not CPPLite Kit but the one from the NetBeans 8.2 Plugin Portal) in NetBeans 18. It works really well besides the GNU-C99 __flash qualifier (and possibly also other GNU-C99 qualifiers).

For example, const __flash Font *unifont = &unifontFont; causes an error marker "Unable to resolve identifier unifont." in the editor.

I have a "Tool Collection" in the GNU family with all the avr-* counterparts and in "Code Assistance -> C Compiler" I have "C Standard" C99. "Configuration Type" is Makefile.

Building the program with make on the command line and also from within NetBeans works fine, it is just the "Code Assistance" that does not seem to be aware of these Named Address Space qualifiers.

Is there a way to tell "Code Assistance" that these are valid qualifiers or to use the GNU-C99 standard?
