treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated #284
Description
I use clice on C source code. Clice warns in the editor "treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated.". And the file is treated as C++ source code, for example I cannot assign T * to void * without a cast.
log:
