non-compiiled code check setting

Hello!

I can't reproduce the issue in a simple project. 

I added -DFOO to CXXFLAGS in my Makefile and reloaded the project (Tools | Makefile | Reload Makefile Project), and it was correctly recognized in my source code - the code inside #ifdef FOO - #endif wasn't marked as non-compiled:

1. How exactly do you define the parameters in Makefile?
2. Is your project loaded in CLion without any issues? I.e. do you see any errors/warnings in the Build tool window if you do Tools | Makefile | Clean and Reload Makefile Project?

Hello

I define parameters like you: `-DFOO` in CFLAGS. 
I have issue for unsupported compiler:

Unexpected compiler output.This compiler might be unsupported.
If you are using GCC/Clang, please report the bug in https://youtrack.jetbrains.com/issues/CPP.

I use avr-gcc compiller.

1. Could you please share the entire output in which you see the warning?
2. Please open any project source file in the editor, call Help | Diagnostics Tool | Show Compiler Infofrom the main menu, and share the entire output with us.

Yes, I can. 

This is entire out, which I see the warning, but It is useless, I think.

Compile project is OK. I have set Makefile Target and It is works.

My define is ‘MB_ENABLE’. Its here, but in my code is MB_ENABLE market still as non-compile.

I installed gcc-avr, binutils-avr, and avr-libc in my Ubuntu Docker container, and I can't reproduce the “Unexpected compiler output. This compiler might be unsupported” warning with a simple Makefile project and the avr-gcc compiler:

Also -DFOO is correctly recognized in the code:

1. Where do you see the “Unexpected compiler output. This compiler might be unsupported” warning? Please share a screenshot.
2. Could you please create a simple project and check if you get the “Unexpected compiler output. This compiler might be unsupported” warning in it?

OK, I find problematic line in Makefile:

CFLAGS += -Wp,-M,-MP,-MT,$(*F).o,-MF,dep/$(@F).d

If I remove this line, everything works fine without any errors. I dont need this feature, so my problem is solved. Thanks you!
