Subject: cgraph aagerror: squash -Wmissing-prototypes warning
X-Git-Tag: 7.0.0~2^2

cgraph aagerror: squash -Wmissing-prototypes warning

Calls to this function are generated by Flex – it normally generates calls to
`yyerror` but we alter the Flex prefix to `aag` – but it does not generate a
prototype for the function. So squash the compiler’s overly cautious warning:

  ../../lib/cgraph/scan.l: At top level:
  ../../lib/cgraph/scan.l:219:6: warning: no previous prototype for ‘aagerror’
    [-Wmissing-prototypes]
    219 | void aagerror(const char *str)
        |      ^~~~~~~~
