VBCC: complain about static int (*calltrap)(...) = (int (*)(...))0xF0FF60;

HELP appreciated! What's wrong with this declaration:

Code:

static int (*calltrap)(...) = (int (*)(...))0xF0FF60;

vbcc moans it as "error 0 - declaration expected", while SAS/C, StormC v3 eat it as beeing OK.

How do I have to rewrite this statement in order to get vbcc to come clear with it?

Thanks in advance,

Michael

GCC gives us a more descriptive error:

Code:

error: ISO C requires a named argument before ‘...’

So for me the following compiles in gcc:

Code:

static int (*calltrap)(int, ...) = (int (*)(int, ...))0xF0FF60;

Sorry I can't test with vbcc, my install is borked at the moment.

Well big thanks! Since this is part of uae_pragmas.h from e-uae src, I guess I'll have to rewrite that module in order to compile. Should be the samm with vbcc... :D

A function with just one varargs argument makes not much sense in ANSI/ISO-C. The va_arg() macro requires the name of the last argument before the '...' to work.
