function definition without parameter list

[Alexander Bernauer]

Hey,

the Language.C parser happily accepts the following code:
---8<---
int f {}
--->8---

and returns the following AST:
---8<---
(CTranslUnit
 [CFDefExt
    (CFunDef [CTypeSpec (CIntType _)]
       (CDeclr (Just "f") [] Nothing [] _) [] (CCompound [] [] _) _)]
 _)
--->8---

But the GCC rejects the code with
---8<---
/tmp/foo.c:1: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘{’ token
--->8---

I am not aware of any language dialect of C that allows function
definitions without parameter lists. Is there any? Or should the parser
actually also reject the above code?

Greetings

Alex
