We will include -Wstrict-prototypes in RPM_OPT_FLAGS via enabling
it for -Wall soon, which will warn about non-prototypes like
void foo();
which cause problems if foo is called before its definition is reached
and arguments with default argument promotions applied do not match
the argument types. For example
void foo();
{ .. foo(1.0); .. }
void foo(float x)
{
...
}
will call foo with a double argument.
Note that
void foo();
is not a valid prototype for a function with zero arguments in C, but
void foo(void);
is. The above case will probably cause a lot of extra warnings.
Thanks,
Richard.
