Cpptools allways force use cl.exe or mingw-gcc. Is it not support other gcc family cross compiler ?

[github0null]

I use cpptools for my embedded project. This project use avr-gcc as c compiler.

The macro: __AVR_ATmega128__ is avr-gcc compiler internal macro.

I explicitly indicate the compilerPath in the configuration, but cpptools allways use mingw-gcc, mingw-gcc not have this macro. And for that reason, my project allways have some intellisense error.

This is my config in c_cpp_properties.json:

Something is causing our compiler querying to fail, so it falls back to mingw-gcc. You may be hitting #9099 . If you run C:\\WinAVR-20100110\\bin\\avr-gcc.exe -Wp,-v -E -x c /dev/null and you see

#include "..." search starts here:

and don't see

#include <...> search starts here:

then it'd be the same issue.

[github0null]

I tried it. this is result

[github0null]

I checked the Language Server log and it seems to be the reason that the compiler of the avr type are not recognized.
