Strange Compile error with Intel CC

[MG12]

I try to use the last version of the Intel C Compler and successuflly added it into Visual Studio 2022.

I run into an compiler error that I dont get rid off.

We used to apply prototype definitions often using forward definitions for structs, like this:

Prototype in a header file:

void testfoo(struct _FAA *nn);

C-Code:

typedef struct _FAA
{
int b;
}FAA;

void testfoo(FAA *aa)
{
aa->b = 0;
}

On compiling I get this error:

code.c(277,6): : error : conflicting types for 'testfoo'
1>void testfoo(FAA *aa)
1> ^
1>code.h(204,6): note: previous declaration is here
1>void testfoo(struct _FAA *nn);
1> ^

Seems the compiler doesnt like our forward declations of structs, but why ?

This was not a problem with the compiler 2 years ago, but now with the recent

download.

Any tips ? Maybe a compiler flag that I missed ?

Thanks you!
