a quick google search turns up the following additional information:

"clang supports the -std option, which changes what language mode clang 
uses. The supported modes for C are c89, gnu89, c99, gnu99, c11, gnu11, 
c17, gnu17, and various aliases for those modes. If no -std option is 
specified, clang defaults to gnu11 mode. Many C99 and C11 features are 
supported in earlier modes as a conforming extension, with a warning. 
Use |-pedantic-errors| to request an error if a feature from a later 
standard revision is used in an earlier mode."
