>Description:
when including both <string.h> and <machine/cpufunc.h> from a C++
source, gcc yields a declaration error:
In file included from ffstest.cc:3:
/usr/include/machine/cpufunc.h: In function `int ffs(int)':
/usr/include/machine/cpufunc.h:109: `int ffs(int)' was declared `extern' and
later `static'
/usr/include/strings.h:44: previous declaration of `int ffs(int)'
>How-To-Repeat:
% cat > ffstest.cc <<__EOF__ && cc ffstest.cc
#include <string.h>
#include <sys/types.h>
#include <machine/cpufunc.h>
__EOF__
