AmigaOS4 support

Hi,

I use macOS to cross compile for Amiga OS 4 and use VS Code as text editor.

As you can see in the screenshot it complaints about to few arguments, but actually this is a feature of the ppc-amigaos-gcc as the first argument is implicit.
Eg an API is declared like this

struct PCIDevice
{
    BOOL APICALL (*Lock)(struct PCIDevice *Self, UBYTE Mode);
    void APICALL (*Unlock)(struct PCIDevice *Self);
}

but called like this
my_device->Lock(PCI_LOCK_EXCLUSIVE);

Without the Self argument. The magic is in the APICALLqualifier that makes the compiler take care of this.

My question is, can I some how make the parser understand this and stop complaining about too few arguments?

Cheers

Start by reproducing the too-few-arguments diagnostic in VS Code with the ppc-amigaos-gcc example using the APICALL qualifier. Trace the C/C++ parser's handling of function-pointer calls and calling qualifiers, then verify that the implicit Self argument no longer produces a diagnostic while ordinary calls still do.
