ISO C90 forbids mixed declarations and code sscanf
- by Need4Sleep
I'm getting a strange error attempting to compile my unit test code,. For some reason the compiler treats my sscanf call as a mixed declaration? I don't quite understand, here is the entire error:
cc1: warnings being treated as errors
