Bejewled Practice: A horrible C mangler

Inspired by this tweet: https://twitter.com/vamchale/status/1193278821740531713. What if we could do so much worse? Write code, or upload a zip that contains C code, and then click the appropriate button to get a download link. Compile by specifying the include path, for example: 

$ gcc -I bjw/ main.c

If your code doesn't compile, please report it to @porglezomp. 



    
Thanks

    

      Thanks for the inspiration to this tweet.
      The rest of this is my fault though.
