lib/strcasestr.c, lib/strings.in.h, lib/strncasecmp.c,
m4/getpagesize.m4, m4/memchr.m4, m4/mmap-anon.m4,
m4/stddef_h.m3, m4/strcase.m4, m4/strcasestr.m4,
m4/strings_h.m4, m4/wchar_t.m4: Added, via gnulib --import

bytes in the longword in question are equal to c. We first use an xor
with repeated_c. This reduces the task to testing whether *any of the
four* bytes in longword1 is zero.
We compute tmp =
((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
That is, we perform the following operations:
1. Subtract repeated_one.
2. & ~longword1.
3. & a mask consisting of 0x80 in every byte.
Consider what happens in each byte:
- If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
and step 3 transforms it into 0x80. A carry can also be propagated
to more significant bytes.
- If a byte of longword1 is nonzero, let its lowest 1 bit be at
position k (0 <= k <= 7); so the lowest k bits are 0. After step 1,
the byte ends in a single bit of value 0 and k bits of value 1.
After step 2, the result is just k bits of value 1: 2^k - 1. After
step 3, the result is 0. And no carry is produced.
So, if longword1 has only non-zero bytes, tmp is zero.
Whereas if longword1 has a zero byte, call j the position of the least
significant zero byte. Then the result has a zero at positions 0, ...,
j-1 and a 0x80 at position j. We cannot predict the result at the more
significant bytes (positions j+1..3), but it does not matter since we
already have a non-zero bit at position 8*j+7.
So, the test whether any byte in longword1 is zero is equivalent to
testing whether tmp is nonzero. */

RESULT_TYPE A macro that expands to the return type.
AVAILABLE(h, h_l, j, n_l)
A macro that returns nonzero if there are

H is 'unsigned char *', H_L, J, and N_L

CMP_FUNC(p1, p2, l) A macro that returns 0 iff the first L
characters of P1 and P2 are equal.
CANON_ELEMENT(c) A macro that canonicalizes an element right after
it has been fetched from one of the two strings.
The argument is an 'unsigned char'; the result
must be an 'unsigned char' as well.

The global period of a string is the smallest index (possibly its

A critical factorization has the property that the local period
equals the global period. All strings have at least one critical
factorization with the left half smaller than the global period.
