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....
