During development, I want to embed notes for myself to do something - for example, on an older 68K compiler, I had put in - the following statement in my C source:
asm(".msg 'Add code to initialize I/O port','w');
What this does, is when I do a build, I get a warning in the output. If I change the 'w' to an 'e', I'll get a build error.
What is the equivalent command for gcc?
