This is the bit triggering from gnulib (CC'd) says it's assuming 'gets'
is declared. Can you see why this isn't the case for you?

/* It is very rare that the developer ever has full control of stdin,
   so any use of gets warrants an unconditional warning.  Assume it is
   always declared, since it is required by C89.  */
_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");
