gcc and g++ allow you to define an extern foction like this:
extern int test(char *c)
{
 return c==(char*)0;
};

Strange, isn't it. You tell this fonction to be extern and you
write it.
Is it a gcc/g++ feature, a bug, or an ANSI-C feature ?
This program compiles without warning, even with -Wall.
And you can't write:
extern int val=9;

BTW, it can be very useful with g++, to allow C fonctions to call
C++ fonctions
Please, anser me by mail.
