That means all the reported issues are due to the headers having been
cleaned up for recent POSIX/Unix specification versions. Duplicated
prototypes have been removed and obsolete symbols have been removed.
Which means that as far as the tests performed by the script go, the
headers files comply to the current POSIX/Unix specification.
[*] Since the scripts are not clever enough for the way gcc handles
include files (namely, putting some of them in gcc-local directory) I
copied over the iso646.h, float.h, and stddef.h headers and ignored the
problems resulting from the splitted limits.h file).
