Because one file uses K&R style function defintions and the other uses a prototype which is ANSI/ISO
style.
Simple example:
file1.c:
int f(int);
---
file2.c:
int f(a)
int a;
{
return a;
}
---
Compile it as:
gcc file2.c file1.c -combine
So this about the following:
int f(a)
int a;
{
return a;
}
int f(int);
Which is questionable.
So I don't think this is not an inappropriate warning.
--------------------------------------------
As an aside, I wish people would stop using K&R style C already.
