--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Since you can test a build with uclibc, can you possibly come up with a
(minimal) patch to make the build work?  It sounds like amending

// OS
#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

with

#include <stdlib.h>

should do the trick?  Can you possibly post such patch to
gcc-patc...@gcc.gnu.org stating how you tested it?

Thanks.
