Could you please give a pointer to the place where this feature is
documented in the ANSI C99 standard? Because it seems that the GCC
crew has overlooked it. If I try to compile:

============
#include <stdio.h>

void myfun(int &a){

a = 2*a;
}

int main (void){

int a = 10;
myfun(a);
}

===========

with

$ gcc -std=c99 reference.c

this is what I obtain:

reference.c:3:16: error: expected ‘;’, ‘,’ or ‘)’ before ‘&’ token
 void myfun(int &a){
                ^
reference.c: In function ‘main’:
reference.c:13:4: warning: implicit declaration of function ‘myfun’ [-Wimplicit-function-declaration]
    myfun(a);
    ^

So my version of gcc apparently does not know about this feature
included in the ANSI C99 standard....
