Both prototypes will be enabled if you compile with:
* __USE_FILE_OFFSET64 defined (which is the case here through
-D_FILE_OFFSET_BITS=64)
* __REDIRECT_NTH defined
and a gcc of version >= 2.x (to enable the later decl).
Later digging shows that __REDIRECT_NTH seems to always be defined.
Though on an amd64, or an i386 having both the prototype with and
without __restrict causes no problem whatsoever.
it seems that this:
#include <sys/stat.h>
int main(void) {
struct stat st;
return stat("/etc/passwd", &st);
}
compiles correctly with an almost up to date etch alpha machine. We
will have to wait for an alpha machine to be accessible to developpers
again to test it further.
