2ident macro

[USSRcoder]

//--- stdout
//identcall ident2call ident2("Hello, World!")
//identcall ident2call ident2call "Hello, World!" 
#define HELLO "Hello, World!"
#define identity(a) identcall a
#define ident2(a) ident2call a

identity(ident2(ident2))(HELLO)
identity(ident2call ident2)(HELLO) 

Unknown why, but ucpp wrong expand this macro:

 identcall ident2call  ident2call "Hello, World!"
 identcall ident2call  ident2call "Hello, World!"

with/out define INMACRO_FLAG;
testing under msvc 2019, w8. Maybe it non c99 macro, but gcc/cl produce correct results.
