I am not sure test:
---
char pstat_getstatic ();
char (*f) () = pstat_getstatic;
int
main ()
{
return f != pstat_getstatic;
}
---
which detects if pstat_getstatic is defined,
is compatible with whopr, which may decide
f is never changed and optimize it to
int
main ()
{
return 0;
}
We need a better way to detect if a function is
available when whopr is enabled.
