Just noticed that on 4.8-STABLE I get a similar effect compiling code
with -ansi. Which is similar, possibly slightly different, but adds
weight for the argument for fixing the ffs() code.
- Example Code ---------------------------------------------------------
#include <string.h>
#include <machine/console.h>
#include <vgl.h>
int main() { return 1; }
- Example Compiler Output ----------------------------------------------
gcc -ansi -Wall -Werror test.c
cc1: warnings being treated as errors
In file included from /usr/include/vgl.h:37,
from test.c:3:
/usr/include/machine/cpufunc.h:118: warning: static declaration for `ffs' follows non-static
- End Example ----------------------------------------------------------
This "implementation detail" might be used by a programmer using C++
or -ansi on a C program, surely it should work ?
