(IS_TAILABLE_FILE_TYPE): Adjust definition also to include
sockets, since that's what you get when reading from a command-line-
supplied pipe on Darwin 7.7.
(IS_PIPE_LIKE_FILE_TYPE): Define.
(main): Use new IS_PIPE_LIKE_FILE_TYPE rather than simply S_ISFIFO.
This same change is also required on NetBSD/sparc-1.5.
Reported by Adrian Bunk.
rather than suffering silently.
Before, expr would silently overflow and wrap around:
$ expr 9223372036854775808 = 0 # $(echo 2^63|bc)
1
Now it detects the problem and exits nonzero:
$ ./expr $(echo 2^63|bc) = 0
./expr: 9223372036854775808: integer is too large
(sparc64, Linux-2.4.28, glibc-2.3.3) that didn't honor utimes'
NULL-means-set-to-current-time semantics.
Remove temporary file immediately, rather than waiting
for configure's at-exit trap code to do it.

_POSIX2_VERSION=1 ./expand -$(echo '2^64+1'|bc)
Before it would act like `_POSIX2_VERSION=1 ./expand -1'.

(longopts, usage, main, validate_file_name):
Add support for new -P option.
Reject empty file names (unless -p is not specified and the
current system allows empty file names).
Change --portability so that is now equivalent to -p -P.
Don't test whether file name is too long, if it is known to exist.
(no_leading_hyphen): New function.
