[Bug c++/29177] New: Wrongly rejects non-template function default arguments in later declarations

[greifel at megatop200 dot com]

8.3.6/4 dcl.fct.default: "For non-template functions, default arguments can
be added in later declarations of a function in the same scope."
(there's a detailed example).

gcc 3.4.0 compiled the following code with no problem but release 4.1.1 rejects
it
(with or without the -ansi and -pedantic flags btw), with:

sjh@mill:~/c++$ g++ -ansi -pedantic x.c
x.c:5: error: default argument missing for parameter 2 of 'int f(int, int)'
x.c:5: error: default argument given for parameter 2 of 'int f(int, int)'
x.c:1: error: after previous specification in 'int f(int, int)'

sjh@mill:~/c++$ cat x.c
int f (int a, int b = 1)
{
   return a + b;
}
int f(int a = 6, int b); // can add default arguments  - 8.3.6/4 page 142

sjh@mill:~/c++$ gcc -v
