I’m not. I’ve been working with C on and off for 30 years. Linux requires GNU extensions beyond standard C. Once you get the basics done, there’s still a lot more work to do. Compiling a trivial program might work. But you’ll hit an edge case or 50 in the millions of lines in Linux.

I also should’ve qualified my message with “in 2 weeks”, or even “in 2 months.” Given more time it’s obviously possible for more people.
