I have an avr-gcc project in NetBeans 18 with the C/C++ plugin (not CPPLite Kit but the one from the NetBeans 8.2 Plugin Portal) which works really well besides the GNU-C99 __flash qualifier (and possibly also other GNU-C99 qualifiers).
Using the __flash qualifier causes an error marker, for example:
const __flash Font *unifont = &unifontFont;
The marker says "Unable to resolve identifier unifont."
Building the project in NetBeans works fine.
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.
Is there a way to tell the plugin that __flash is a valid qualifier or to use GNU-C99 by setting -std=gnu99 somewhere?
