In the documentation ("Declaring Attributes of Functions"), I find:
"The keyword `__attribute__' allows you to specify special attributes
when making a declaration." However if the attribute is repeated at the
definition of the function, I get an parse error (according to the
documentation):

int foo1(void) __attribute__((stdcall)); 
int foo1(void) __attribute__((stdcall))
{ 
    return 1; 
} 
bug-43119-2.c:3: parse error before `{'

When using the now undocumented way of moving the attribute before the 
function name, neither the parse error nor the type conflict occur:

int foo1(void) __attribute__((stdcall)); 
int __attribute__((stdcall)) foo1(void) 
{ 
    return 1; 
}
